CAD Parts List

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below:

  • case
  • bottom-cover
  • holder-acrylic
  • holder-strip

Build Volume

The parts require a 3D printer with a minimum build volume.

  • 210mm (X) x 70mm (Y) x 90mm (Z)

CAD Assembly

The QT Py is installed into the built-in holder on the bottom cover. The bottom cover snap fits onto the case. The LED holder is fitted into the center opening of the case. The acrylic holder is placed on top of the LED strip holder and held in place inside the case. The acrylic pieces are press fitted into the slots of the acrylic holder.

Acrylic Shapes

Download our pre-made shapes to get started. Each acrylic piece features a 20mm tab for press fitting into the 3d printed acrylic holder.

Add custom SVG graphics to the shapes using your preferred software.

The 1/4in thick acrylic pieces can be cut with a laser cutter or CNC mill.

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.
