I made a different switch with reed relay. On the bottom I added a box for the battery so it is no need for a screwdriver to change battery.

I watched Terrahawks British Sci-Fi television series on TV as a kid and always wanted to have my own Sergeant Major Zero puppet. Such toy was not available to me in the nearby toy shops. So now, as a big kid I made myself one, together with it's enemy Cube. It is sometimes used as stress ball on my office desk, and is a good conversation starter.

You will also find attached model of the cube, so 3D print as many as you like and go stage some attack!

To avoid rolling away zeroid from my desk, I printed variant which has flat surface on the bottom. Round and flat versions are attached so pick any you like.

I decided to share design for anyone who enjoyed the show. if you have not seen Terrahawks yet, there are some clips on youtube so please do!

This is a Hairy Lion. As the name says it is lion with hair.
This is a remix from Geoffro's design Lion HD (no supports required).

UPDATE #2: I made about 3 times bigger version. It has a lot of hair and they are also very long.
Watch Joel Telling's (3D Printing Nerd) video about it: https://youtu.be/OTXPU2P-ElE

UPDATE #1: I made 50% smaller version. It should only take about 1-2 hours to print. But you must be much more careful when cutting the hair. This model has much less hair, so if you break or pull out too much hair, there will be visible bald spots.

The hair is connected to sacrificial wall, which is removed afterwards.
(See picture: post_processing.jpg) You can also try hot water to form the hair. Anyway, be careful not to burn yourself.

There was a request to add a brim to sacrificial wall. So I made it: "Hairy_Lion_with_brim.STL"

This was printed with ABS, but it should also work with other materials. If you are having problems, adjust bridging settings in your slicer.

3D print and assemble your own classic Islamic-style artwork by using Girih tiles to build intricate woven strapwork!

The tiling pattern in the photo is rotationally symmetric. On the left are the basic colorful tile shapes. Towards the middle we have started to add the overlaid strapwork, which is completely determined by the tiles. On the right, we added gray mosaic tiles to obscure the original tiles and reveal the strapwork pattern.

Girih tiles are used in Islamic art and architecture to create intricate woven strapwork patterns. The underlying periodic patterns that create these designs are related to Penrose tilings and predate the formal mathematical discoveries of such tilings by at least 500 years.

Made a bigger, badder brother to my original Bug Bot (http://www.thingiverse.com/thing:1065468) with some design improvements to make it easier for little hands to assemble:

+Built in battery case (I will upload as a separate piece in upcoming days)
--Using metal zip tie idea** from original Bug Bot, the contacts are extremely easy to make.
--Jumper cable cutouts at all battery contacts for solderless connections. The battery pressing up against it gives enough resistance to hold jumpers in.
--Easy to add ON/OFF switch with 2 small screws and a small piece of metal zip tie. (OR, you can place a jumper between the two batteries for constant power.)

+Bug shaped base/body

+Larger area for vibration motor.

NOTE: I am aware that spiders have 8 legs versus 6 (hence the name "BUG Bot" and not "Spider Bot.") I experimented with 8 legs and found it to be a more difficult setup than 6 (especially for little hands.) If you want to make it more accurate, you can easily drill two more holes. Happy building and good luck!

**I don't work or sell the metal zip ties, just sharing a cool idea I had that worked better than I had expected :-)

I needed a little stand to hold my Raspberry Pi Touchscreen on my desk while I'm working on software for it. You need to print two of the legs. It needs four M3 screws to attach the them. M3x10mm screws will work but M3x12mm with a washer works even better. I printed mine with 20% infill.

This is for the 7" touchscreen made by the Raspberry Pi Foundation. https://www.raspberrypi.org/blog/the-eagerly-awaited-raspberry-pi-display/

[UPDATE 2016-03-27]
I noticed recently the glass on my touchscreen had slid down out of alignment with display underneath. It appears over time the heat of the display backlight causes the double stick tape between the glass and display to soften. If unsupported the glass begins to slide down. Mine had moved down about 5mm. To address this problem I uploaded a new version of the stand that has a lip for the glass to rest on and prevent this. I was able to push the glass back into place with the help of a heat gun. Also included in this update is a version with a notch cutout to allow for USB powering of the display.

It's probably finished but is marked a "Work in Progress" http://www.thingiverse.com/thing:1036486

This is a replica of the popular Bongo Tie rubber band fastener for holding things together, just add a rubber band! These are also great for attaching a cable to a pole or two long or bulky objects together.

It's a few millimeters shorter than the original but this makes it more stable to print and fits better with normal sized rubber bands. I may add a different sizes in the future.

Now, you too can own a historic piece of visual theory!
Wowza, the simulacra never smelled quite as much of hot plastic ever before!

Get your's before the aura on this one of a kind piece fades!

Keyboard AKAI APC Key 25. with more or less precise measures. I used photos and physical model to get proper measures, so it's not totally accurate, but close enough i guess..

http://www.akaipro.com/product/apc-key-25

Small image of four-legged animal using only one servo motor. The legs have to be adjusted with a little heating, such that the total weight is in balance. Housing for the battery is double for 2 x AAA size, which is also the holder for PCB.

This is based on a reconstruction of a 36,000 year old bone flute found at the Divje babe I cave site in Slovenia. This 3D-printable version was created based on the work of archeologist Ivan Turk. The figures used to trace the flute's shape are from Chapter 15 of "Origins of Music" (©2000 MIT Press).
I tried to copy the shape of the flute as closely as possible, and ended up with a flute that is pretty difficult for me to play, though I'm not a professional player. I have at times managed to play several notes with it. (You can find videos of the reconstruction made by Ivan Turk et. al. being played by a professional player.) It's basically an edge-blown flute with a diatonic scale, with the opening covered for some notes.
Please iterate on the design or comment on how this flute can be made more accurate and/or easier to play.

KeyV2 is out!

This library is deprecated, and a new version has been released! please check it out here: KeyV2

Summary

I got halfway through making a parametric novelty keycap base before I realized there are decidedly few basic keycaps on the thingiverse website, so I took a detour to make a good one. This library has slowly grown to where you can generate keycaps in four different layouts in any length or height you desire! They are not quite drop-in replacements into existing keysets yet, but work great as a set, escape key, WASD cluster, top row, or as a base for an artisan.

Heavily modified from Kekstee's original Skull keycap to refactor, remove dxf files, add a dish, parameterize, and add a square keyswitch connector: https://github.com/kekstee/3dprint

Makerbot's customizer is great, but it's hard to zoom in and sluggish with spherical dishes, so you might be better served booting up OpenSCAD. Also, using OpenSCAD opens up a whole new level of customization! Due to the complexity of the key profiles things like dish depth, top skew, etc. can only be controlled from inside OpenSCAD. There are a lot of comments as to what things do so don't be afraid to dig around!

Features:

• Many imitation key profiles supported! DCS, SA, DSA, and G20 for now. No OEM until I can find a good data sheet :(
• Square Cherry key connector stem; easier to print. Circle and Alps available.
• Stem inset now supported! allows you to print keys that will sit lower on the keyboard than before. you'll need to print with some kind of support.
• Multiple dish types that affect the top and bottom, so keytop thickness is uniform throughout. Dishes are correctly created using a bit of trig, so they expand to arbitrary sized keycaps. Inverted dish types for spacebar / funky keyboards supported!
• Keycaps can be arbitrarily wide or tall! note that for extra large keycaps you might need to turn up rounding on the dishes
• Stabilizer supports! requires some digging for now, will add better support later

Experimental features:

• Experimental ALPS compatibility!
• Experimental rounded keycaps! Requires SCAD knowledge; replace key() with minkowski_key(). Will take FOREVER for anything with a dish due to polygons. G20 does not have a dish. results are pretty, but if you don't have a really good 3d printer you can safely skip.
• Experimental ISO enter in the works. technically it is there, but it is the wrong size. you need to switch any use of shape_hull() for ISOEnterShapeHull(). I don't own any keyboards with it either so I have no idea if it actually fits or if it needs stabilizer holes (I assume so?) I just have keys I'm comparing it to from a grab bag.

Road to V2:

• just need to do the customizer script now, with any luck we will be releasing soon

Behold the Sphero Landstrider! This accessory allows Sphero to walk about on his own 8 legs. This unique powertrain harnesses Sphero’s rotational motion and converts it into an elegant stride inspired by the Theo Jansen mechanism. Future versions of the Landstrider could include interchangeable gears for teaching young students the principles of mechanical advantage and general engineering skills. The powertrain could also be adapted to power other vehicles with wheels, tank treads, or even propel a boat. All rights reserved #make5000. http://youtu.be/Pf7Pm4YyCeg

This is my first 3D design and one of my first prints on my Printrbot Simple Metal. It's a weight designed to hold down musical keyboard keys for ambient, electronic, drone, and
experimental music. When you need more than 10 fingers, reach for one of these.
Print the two parts, fill with 40 pennies, snap the pieces together, and voila! This should be heavy enough to hold down even heavily-weighted keys. I designed it with ramps on the side panels to help balance it on the smaller ebony keys. All sides can be used as the press-down side. Please let me know your experiences!

I'm including two versions for download -- one with the Circuit Benders' Ball logo and one without. Feel free to customize with your festival, band or company name.

Smartphone holder, flexible to hold many different phone sizes. It is compatible with OpenStructure ecosystem.

Examples; as "tripod" (with copper wire, used for legs):

• shooting still video, similar as Joby tripods
• video conferencing
• in car use
• attaching or hanging smartphone for using it as LED torch

This is my 3D interpretation of Amanda's walker linkage system. I'm planing to do full scale model, but first I need a workable printed model.

Scale is 1:1 to Amanda's Mathematica's units. Her thesis on this subject can be found here: http://www.amandaghassaei.com/mechanical_walking_machine.html

This is first model and it is not (properly) walking yet. It's basically a proof of concept.

I'm allready working on a second model, just arhiving that one here.

Counting can be really fun with these easy-to-print body parts. They are a big hit at a special needs school in Slovenia where we are using them since this spring.

The children like them much more than blank beans or beads and learn about their body and numbers at the same time. As you can see in the pictures we ask kids to put the correct number of objects on the dots next to each number.

We find using physical objects helps associate numbers to their symbols. A pair of feet, ears and a head are included, all sized appropriately for little hands to grab. We usually try to combine different topics in one lesson when teaching these children, as in this case the human body and counting.

Ears are half-size from the original, the head of doctor Oh is shrunk to 30%, both otherwise unchanged from the referenced sources. The foot was leveled and mirrored to make the pair. Not sure where it comes from, we tried searching for it but nothing came up. Use support to get better quality prints - only a very small amount is necessary at the bottom of feet and chin.

We hope you like them and will make more similar ones!
