Open Hardware CupCake
thingiverse
Do you want to make Open Cakes?? Ok, so you just need the Open Hardware CupCake!! . I really did it from the scratch using OOML ( http://iearobotics.com/oomlwiki ) but the idea is of http://www.thingiverse.com/irts. Instructions You can print directly the STL files, scaling them at your wisth. The pusher is slightly smaller than the hole in the base, so it should work. I do not really know whether it will break the paper :S. You can also modify the source code. Download the .zip file. This is C++ code and needs to be linked with the C++ OOML Library. Follow the instructions on the wiki page ( http://iearobotics.com/oomlwiki ) on how to install OOML.
With this file you will be able to print Open Hardware CupCake with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Open Hardware CupCake.
