Good-Fast-Cheap

This CAD model was designed by Oskar van Deventer, copyright (c), 26 February 2025

Good-Fast-Cheap is a management fidget, inspired by this YouTube Short ( https://www.youtube.com/shorts/jfyUltOcTZs ). The fidget illustrates that you can choose only two out of those three. This is also known as the devil's triangle. A little chain and some magnets push up the third button, whenever two buttons are pushed down.

These are the additional (non-3D-printed) parts for this puzzle.
-A piece of commercial-of-the-shelf ball chain. I measured the balls to have a diameter of 2.2 millimeter, and a spacing of 3.08 millimeter.
-Twenty (or fourty) small cylinder magnets with 3-mm diameter and 2-mm thickness: https://www.supermagnete.de/eng/disc-magnets-neodymium/disc-magnet-3mm-2mm_S-03-02-N.
