A pull string helicopter that flies well and is easy to assemble.


ABS is the recommended material for best part survival.

As requested SolidWorks 2011 source files are posted. Blade profiles are not optimized. Try to design better shapes that can be easily printed without support and upload your progress!

To see it flying click the video button or watch it on [You Tube](http://www.youtube.com/watch?v=r-lhAp11iZY)

First of all: Yes, it flies wonderful, easy to fly with surprising self stabilisation. But a little bit faster as motor glider generally use to fly ;-)
And the best off all: It lands by itself...

This fan duct will send the electronics cooling air away from the heated print bed and eventually out through the side of an enclosure. The mounting screw holes are all placed relative to the corners of the base. You might need to adjust those for your needs.

n-Sphere Tiles
Designed as an educational toy for my son, the n-Sphere toy is a little puzzle box with no wrong answers. The sphere can be assembled any combination of 6 tiles oriented in any rotation and will always yield a continuous topology of ridges and grooves along the outer surface.
This version is designed with a flat base surface so no support needed with the makerbot.

A small bottle and screw cap that you can print on your 3D printer.

• Size: 95 x 95 x 40
• Inner volume: 139 cm3
• Plastic volume (with cap): 20,5 cm3
• Thread: Screw cap uses same thread as common soda bottles

I wanted to print out one of those nifty gear rings for a friend, but my printer can't handle detail that fine, and PLA isn't strong enough for those tiny gear teeth anyway. So I redesigned it from scratch for a larger scale, a bracelet instead of a ring, for something my printer could print.

This piece is held together purely by friction and spring pins - no glue or screws required. It should also be printable on nearly any machine, even if you only have a 120mm bed. Mine was printed in PLA, but ABS should work too.

Parts of the design were based on the involute gear SCAD and Emmet's locking pin design. The parts were all drawin in Autocad - I have no openscad source files to share.

Update - reworked all the files to be easier to assemble and less likely to spring apart when you rotate the rings. Also, I have updated the autocad drawing files used to create the stl files.

Similar to previously posted bottle but remodeled to make inner and outer perimeters of layers remain evenly spaced.

Pictured print is 1 perimeter 5 solid top layers, 5 solid bottom, no fill.
.25 layers 0.4 wide extrusions, 50mm/sec speed.

Printed on an Aluminatus in ABS.

I accidently broke one of the clips which keep my backpack closed, so I designed a printable replacement.

Hope some of you find this useful :)
Enjoy!

MakerBot Customizer Challenge Runner-Up !

A Cable Tie that works and can do the heavy lifting ! Can be customized for various purposes including a hole for a Screw and a Release Tab.

A model made from one of da Vinci's drawings. This is an elegant and simple version of the 'overbalanced wheel', which supposedly has more weight on one side and will spin forever.
A fun model to make, with an interesting history.

This is a 48 inch wingspan sailplane of my own design. All parts have been 3D printed using PLA. The wing has been test flown, but the entire assembled plane has not yet been tested. The wing uses the Eppler 214 airfoil.

**** Two files updated 18 May 2013 ****
The two files are the Vert_stab and Fuselage_tail files. A very minor change was made to the vertical stabilizer by removing some material at the bottom of the control linkage channel. I've added a feature in the fuselage tail part to allow trapping the sheath end of the flexible control cables using two set-screws. This prevents having to cement the sheath in place to prevent movement.

You can now buy this case from my Shapeways shop here: shapeways.com/model/997471/iphone-gear-case-for-shapeways.html?li=modelEdit

This is a version of the iPhone Gear Case that I completely designed and drew myself. It is much easier to print than the first case, as well as being stronger and a better fit. The areas beneath the buttons and sliders has been removed to make them easier to use, and a cutout has been made around the headphone port so bigger jacks will fit without having to remove the case. The edges of the case are also tall enough to prevent the screen from touching when placed face down. I added a bevel to the ledges that hold the case onto the phone that makes the case very easy to print without support.

Here's a video of the gears in action

I got the Geneva Mechanism idea from jessed, and used msruggles' solidworks gear generator to create the gear profiles.

This is a sneak preview of my derivative of a Filament Extruder. The focus is on trying to print as many parts as possible.
This thing is part of my final thesis in my mechanical engineering degree. Once finished all printed files and drawings will be published (if I get the OK from my University).
First tests are promising but a few things still need to be modified.

This i were it started, here´s my first go at creating a printable rc car which later resulted in the OpenRC Truggy car.

I learned alot from this car and so it´s a little bit different. It´s has belt drive and is built on a aluminum plate so it´s not as "printable" as it´s successor (http://www.thingiverse.com/thing:42198).

If you like build one of your own, the belts are from an Xray car (don´t remember the model) and bought at Amainhobbies.com, driveshafts are from Conrad.com.

If somebody would like to build one let me know and i will post some more info!

Here´s a short testdrive video: youtu.be/HpFrq0iMeAE

Here are three snowflakes generated using 2 of the 17 two dimensional space groups, p6 and p6m. The term "two dimensional space group" is a crystallographic one; in other fields they are called the plane groups or wallpaper patterns. P6 and p6m are the only two dimensional space groups which have 6 fold rotation axes and are therefore suitable for making snow flakes.

The openSCAD code uses the equivalent positions of p6 and p6m to place hexagons within a unit cell. P6 has 6 equivalent positions and p6m has twelve. Adjacent unit cells can be generated to form sets of 7 or 49 cells.

Any shape can take the place of the hexagons and objects can be placed anywhere in the unit cell. The algorithms ensure that the space group symmetry is obeyed

Example snowflakes are:

snowflake_p6m_c1.stl - composed of 6 hexagons, 1 unit cell
snowflake_p6m_c7.stl - composed of 4 hexagons, 7 unit cells
snowflake_p6_c49.stl - composed of 3 hexagons, 49 unit cells


Dxf and openSCAD files are included.

NEW! as of June 17.

This is now a complete modular rocket system!

Pick a nosecone, body tube(s), fincan, nosecone coupler, and voila! A semi custom printable rocket!

I plan to be adding new sections on a regular basis so check back often! Feel free to leave feedback if there is some feature you'd like to see that isn't up yet :)

Important dimensions to make compatible modules:
Tube Outside Diameter - 1.75in
Tube Inside Diameter - 1.667in
Coupler Tube Outside Diameter (tight): 1.663in
Coupler Tube Outside diameter (looser): 1.659in

NOTE: The designs are closely based on the Legacy design and should work well, but many of them are still untested. I'm working on it, though.

This is a flexible library for GoPro mounts. I made it also customizer-friendly so you can design your very own mount and print it directly.

Of course you'll get the basic 2- and 3-arm mounts (to build upon), but it also features useful extensions such as handlebar / seat post / threaded rod mounts and options. Check the pictures and the customizer!

This is the fan module add on for the Brabeast thingiverse.com/thing:48087 which is based upon the famous walking Strandbeest from Theo Jansen ( strandbeest.com ). It is modular clip together system that is 3D printer (FDM) friendly just like the original Brabeast. The fan has a sun gear driving some planetary gears, there is a split annulus (always makes me snigger) gear which achieves a very high reduction (86.4:1)

Based upon the famous walking Strandbeest from Theo Jansen ( strandbeest.com ). This is a modular clip together system that is FDM printer friendly. No support required.

I have curved the links in an organic way such that the shape of the leg section looks ahem "bra" like, hence the name.

My own design of a tripod mount for a GoPro camera. Has a hex hole in the bottom for a 1/4-20 nut and space above that for the bolt.

I printed with 50% infill to make it strong and 4 perimeters to reinforce holes.

printable light Frame with holes for all buttons microphones and cables.
including 3DM-File(nurbs)

Designed to fit into the top of a telescoping broom pole.

I took inspiration from raster's original design, but added traps to lock the camera in place. Also added some lens protection, in case the thing falls over.

Also, check out my lens cap for this camera: thingiverse.com/thing:39880

GoPro Helmet Mount

This is a tripod mount for GoPro cameras. You will need a 1/4" screw nut for the bottom. The other screw and nut you can use from the equipment that comes with the camera.

Gopro Flat Mount

Frame holder for the GoPro Hero3 camera. Openings for USB and SD card, both mics, shutter release and WiFi button. Battery is also accessible without putting the camera out of the frame. Easy fix with a flexible catch.

NEW VERSION 2.3:
I had the issue that the catch has broken. Also the WiFi button was often pressed when putting the camera in or out. The new version 2.3 has a stronger catch and a small gap avoiding pressing the button. Have fun...

Updated with minor changes after I had printed this!!!!
