We tested the shredder with gummy bears, paper and popcorn ;-)

Our STL-files are a little bit larger, because you get high quality and high resolution STL-files to get a perfect printing result. Also, we regard the tolerances of the 3d printing process in our 3D STL-models. So please print the models with the recommended print settings.

We are a small, but very creative team, that designs different projects from electronic, 3dprinted or laser cutted components. You will find more information about us under www.jtronics.de
