3D Printed Box

STL files for 3D printing will need to be oriented for print using either FDM or SLS machines. Parts were built with PLA filament.

STL file for printing may be downloaded using the link below.

The box was sliced with CURA using the settings below

PLA filament 205c extruder
0.35 layer height
No supports

round_eyespi_display_box.stl

Original Design File

The box was designed using OpenScad, find the source code for it below.
