A friend of mine wanted a smaller/simpler mount for his GoPro for timelapse runs. Leaves all of the buttons and ports open for use so the camera can be plugged in and operated easily during long capture sessions.

My legallyboundcivilunionlifepartner...thing wanted a Michigan M cookie cutter. How could I refuse the possibility of delicious cookies.

Also, GO BLUE!

Edit: Made a few subtle design changes.

The journey to the center of the earth just got a whole lot easier!

If I do a dual color version it will be a while, so don't hold your breath.

NOTE: The STLs are big. You may have to slice each piece individually just to keep the program from crashing.

No assembly required! ...except maybe some paint.
Loosely based on the F-86 Sabre:
en.wikipedia.org/wiki/F-86

A variation on all the Iris Boxes out there.

Anyone for doing a mashup with the two color globe?

STLs are up as build plates (2x).

Improvements from previous versions:
1. Improved printability. Should be able to print all parts without supports
2. Added and improved clearances.
3. Thickened up some of the thinner sections.
4. Pins are compatible with tbuser's Toy Robot Toolkit.
5. Blockbot now has a backpack/pen holder/rocket launcher tube/use your imagination thing on his back.
6. (V3 to V3.1) Pins printed horizontally for strength.

Big thanks to Lochemage for various design input.

I made the design shorter and a little smaller to reduce cost/time to print. I also added 6 holes (5 in the pawn) in the bottom to accommodate 1/8" cubic magnets. I think for my application I only need three magnets in each piece, but it's easy to have extra designed in rather than trying to drill them later.

I found this video and wanted to make my own. One nut goes on right handed and one goes on left. All overhangs are 50deg so it should print without trouble.

Update:
In case you missed it in the comments, the original screw and video were made by VeryWetPaint (http://www.thingiverse.com/VeryWetPaint).

A turners cube is a great way to test your skills on a lathe, mill or even a drill press if you've got a few screws loose upstairs. This one will test your skills on a 3D printer. This is a complete opposite of the classic turners cube with the rounds on the outside and the squares on the inside. 100mm OD.

As always, super bonus points if you print this out and post the pictures.

Twisted version for those who are feeling especially brave.

Another transformer. I was going to wait till I had finished detailing everything, but I figured the sooner it's released the sooner someone can start having fun with it. Files in SW2011. Seeing how it's taken me several months to get this far don't hold your breath on me finishing any time soon.

Edit 1: Stripped out all detailing so the files are a blank "canvas" and added STL and STEP.

Edit 2: thingiverse.com/tbuser has designed some snap together pins. Now I just need to apply them to the model. Check out his design thingiverse.com/thing:10288.

Edit 3: Superseded by V3.

This uses the spreadsheet from thingiverse.com/thing:7881 as a design table for a Solidworks part. Tested from 3 to 100 teeth at pressure angles of 14.5, 20 and 25deg. Currently only does straight spur gears, but it's really easy in Sldwrks to make an internal or helical gear.

I realize only a minority of people on this site use Solidworks. I use it a lot, and I'm all that matters in the end :)

This is a spreadsheet that will generate a list of points for half a gear tooth (image shows CAD result for 3 teeth) depending on the number of teeth, pressure angle and profile offset. From there you can load it into your CAD software of choice.

I've based this off of the equations and methodology from the following:
school.mech.uwa.edu.au/~dwright/DANotes/gears/appendices.pdf (Appendix B)
and:
school.mech.uwa.edu.au/~dwright/DANotes/gears/generation/generation.html#top

I've given up on trying to code this in any way.

Turret themed chess set for a board with ~1in squares.

I'm working on making a chess board and due to certain constraints, I needed smaller than usual chess pieces (~1" base). Seeing how I was already going to be making them I figured I'd create my own design instead of just scaling someone else's. I purposely stayed away from too many details on the pieces because my printer and I are in a disagreement regarding calibration and I don't want to spend my all my free time cleaning up prints. I would love to see someone detail these out (wink wink nudge nudge).

A shortened version on the Iris box to make printing a little faster.

Inspired by thingiverse.com/thing:4244 this is a box that opens when you twist the outer rings in opposite directions. See this video by Labmat: flickr.com/photos/matthewlaberge/5101233486/

Edit I: Design has been modified to increase the clearance between moving parts. I've also centered and oriented the parts in better positions for printing.

Edit II: Design files posted. DXF, STEP and the original CATpart for those with access to Catia. Thanks to everyone for your photos, videos and design feedback!

Edit III: Be sure to check out Jon Hodgins' version: thingiverse.com/thing:5589

Inspired by the Easy as PI box (http://www.thingiverse.com/thing:3817) and the A-Mazing Box (http://www.thingiverse.com/thing:1481). The combo is as easy as PI... to 15 figures.

Wade's geared extruder modified to work in a Makerbot. This is still in the experimental stage, but my MakerBot is out of commission for the time being so I thought I would release it for someone else to try until mine is back up and running. I've included step files in case anyone wants them.

UPDATE: Moved axis on M8 extruder block (stl only).

Printable turners cube. Haven't tried printing it yet, but it should work.

Nice test piece for a Makerbot and it looks cool to boot!
This is version 2. The printed part pictured was version 1. V1 had some sections that were a little too small and chunks broke off while I was cleaning up the part. V2 should solve this problem.
