FDM 3D Printing

These parts are optimized to print with desktop 3D Printers capable of printing in ABS or PLA material with a minium build area of 100mm x 100mm x 90mm.  The two parts are designed to print without any support material. 

Light Diffusion

The coinDiff.stl part should be printed in either transparent or a light colored material. This is the part that will diffuse the LED so that the question mark logo in the cover illumates.

The standard case design fits a tiny 100 mAh LiPoly battery for maximum portability.





10% infill

90 feed

120 travel

no supports or raft

all three parts should take about an hour total to print

Slicing Software

The recommend settings above should work with most slicing software. However, you are encouraged to use your own settings since 3D printers and slicing software will vary from printer to printer.

PLA or ABS Material

We recommend using PLA material for an easier print with high quality. The tolerance has been tested with PLA filament but should also work with ABS. The parts do not require any support material or a raft.
