3D Printed Parts

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 using PLA filament. Original design source may be downloaded using the links below.

3D Printing Service

These parts were made using JLCPCB's 3D printing service. 

Use the following options for matte black resin parts.

• 3D Technology: SLA(resin)
• Material: Black Resin
• Color: Grayish BLack
• Sanding: Yes

This clear die was make using PCBWAY’s 3D printing service. UTR-8100 transparent resin with spray varnish finish option. This is a costlier route, but delivers an injection-molding-like appearance that would be difficult to achieve any other way.

The numbers were hand-painted to make them “pop.” It’s lovely in a 1990s clear electronics craze way.

CAD Assembly

The two halves are joined together with neodymium magnets.

The mini oval speaker is secured to the built-in holder on the Half-A part using the included sticky adhesive.

The 400mAh battery is secured to the mini oval speaker using the other side of the sticky adhesive.

The Feather is secured to half-A using two M2.5x8mm long screws.

The slide switch is press fitted into the built-in holder on half-A.

The cap and counterweights (2x US penny coins) are press fitted into the built-in holder on half-B.

Dual Extruder/Multi-Material

These STLs have been created for FDM 3D printers with multi-material capabilities.

The numbered labels have  been separated from the D20 halves.

Each type of machine features their own software for slicing.

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 boards, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.
