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.

  • heart-case.stl
  • itsy-reset.stl
  • itsy-cover.stl
  • itsy-case.stl

CAD Explode

The ItsyBitsy and Lipo backpack snap fit into the case. The ItsyBitsy board is secured with mounting taps. The slide switch is inserted into a little holder built into the case. A small button fits over the reset button. A 500mAh lipo battery is placed over the components. The cover is fitted over the case and snap fits. 

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

Design Source Files

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