Summary

This is a 2-post rack for use with a PiDP-11 vintage computer kit from https://obsolescence.dev/. I printed mine with Overture PLA Professional but any quality filament should work fine. You will probably need to enable supports on the right and left posts. I designed the posts to accept an M6x9 threaded insert (https://www.amazon.com/dp/B0CS6YCWHD) for an M6x10mm button head screw (https://www.amazon.com/dp/B0DP4W8895) to hold the base and post together. Note that the base will work on both the right and left hand post sides but the posts themselves are mirror images of each other. I added stick-on rubber feet (https://www.homedepot.com/p/Everbilt-1-2-in-Clear-Self-Adhesive-Round-Bumper-16-Pack-41-H1007/328914157) to the bases to prevent the rack from sliding around while toggling the PiDP-11 switches.
