SlateKey — Case-based key management

SlateKey is my take on stylish key management. No more jingly-janglies, just a sleek case for holding your keys. You only use your keys 1% of the time; 99% of the time you're just carrying them with you. Some assembly required. You will need:2 x Countersunk M3 Bolts of the same length — 16mm / 20mm in length for the 4/6 key variants. Any length works, but you will need to print your own spacers.2 x M3 heat-set inserts. The model is based on inserts with 5 mm diameter and 4 mm of depth.Soldering iron for placing the inserts.If you don't have a soldering iron or don't want to use inserts for whatever reason, using an M3 tap directly also works (after modifying the hole size), although it looks less elegant without a bottoming tap. If you have any other comments or feedback, I am very glad to hear them. Thank you.
