Trinket Platter

thingiverse

This is a simple 3D printed platter to hold the Adafruit Trinket, a power jack, and a wire strain relief. The STL file as well as the OpenSCAD source are available. Although this design has a 90-degree corner, that corner has a lot of strain-relief. The outside edges have quarter-circles. The inside corner edge is rounded, not sharp. More information at the blog post: http://netninja.com/2013/11/16/introducing-the-trinket-platter/ OpenSCAD source is committed to the GitHub project page: https://github.com/BrianEnigma/trinket-platter Instructions Print it as-is. You probably want a more dense infill than your printer default. Hardware you will have to supply: An Adafruit Trinket A panel-mount power jack. Mine was a standard Arduino 2.1mm jack. Unfortunately, I can't tell you where to get one exactly like mine. It was in my parts bin, possibly from Radio Shack, possibly from Digikey. The through-hole threaded portion has a 7.6mm outside diameter. The panel hole is just a bit larger than that. If you need to adjust the hole size, it's easy to find the value in the OpenSCAD source file. M2 screws and nuts to attach the Trinket. Both the screws and nuts I used were from McMaster-Carr. A zip-tie to hold and act as strain-relief for any wires going to and from the Trinket. Just zip-tie any wires to the oval hole.
