PyBadge

In this project we’re making a case for the Adafruit PyBadge. This 3d printed case is designed for a lanyard so you can use it as a conference badge. 

The case is 3d printed in translucent PLA and does not require any support material. A little actuator fits inside the case so you can easily trigger the reset button. The PCB press fits nicely and doesn’t require any hardware screws. The top cover features cutouts for the display and all the buttons.

MakeCode Arcade

MakeCode Arcade is a block based editor for programming your own games. It’s designed for beginners and features tutorials so you can customize them or build your own. The built-in tools like the sprite editor, let you easily create assets and animations.

The Adafruit PyBadge pairs with MakeCode so you can program and upload yours games over USB. With MakeCode Arcade, you can build platforms, side-scrollers, shooters and puzzle type games.

3D Printed Parts

The parts in this kit are designed to be 3D printed with FDM based machines. STL files are oriented to print "as is". Parts require tight tolerances that might need adjustment of slice settings. Reference the suggested settings below.

CAD Files

The fusion 360 source file is included and features original sketches and feature timeline along with easily editable user parameters. The parts can further be separated into small pieces for fitting on printers with smaller build volumes. Note: STEP file is included for other 3D surface modeling programs such as Onshape, Solidworks and Rhino.

Settings

Use these settings as reference. Values listed were used in Ultimaker's CURA 3.X slicing software.

  • 0.2mm Layer Height / 0.4mm nozzle
  • 0.38mm Line Width (inner & outer widths)
  • 40mm/s printing speed
  • 20% infill
  • Supports: No

CURA Slicing

Parts were sliced using Ultimaker's CURA 4.x software and tested with an Ultimaker 3 and Flashforge Inventor II. The kit requires a minimum build volume of 150mm cubed. No support material is necessary for any of the parts. Double check parts are positioned in the center of the build plate before printing. 

Design Source Files

The enclosure assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like the board, displays, connectors and more can be downloaded from our Fusion 360 CAD parts github repo.
