3D Printing

3D Printed Parts

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Original design source may be downloaded using the links below.

  • icube-frame.stl
  • icube-bottom.stl
  • icube-case.stl
  • icube-cover.stl

Case

The ItsyBitsy is press-fitted into the case. Tabs built into the case hold the PCB in place. The USB port is accessible on the side of the case. The top cover snap fits onto the case and has a slit for pass-through wiring. 

PolyCube

The frame of the cube is split into two pieces to allow for support-free 3D printing. The bottom half features posts for press-fitting into the frame. A hole on the corner allows for wiring to pass-through. Acrylic panels are press fitted into the six sides of the cube. 

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like Adafruit's board, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.

Slicing Parts

No supports are required. Slice with setting for PLA material. 

The parts were sliced using CURA using the slice settings below.

  • PLA filament 220c extruder
  • 0.2 layer height
  • 10% gyroid infill
  • 60mm/s print speed
  • 60c heated bed
