BKS Key Cover

Since I could not find a model for keys of the "BKS detect" brand common in germany, I made my own very basic version. The model can be printed in basic PLA without supports standing up (you might need to rotate the model in your slicer). The key simply slides in from the top. The cover is loose by design but won't come off if you attach it to a key ring but it will slide a bit up and down when pushing the key into a lock. This can cause the ring to break if you push too hard or the layer adhesion of the print is not strong enough. Also fits Börkey BO-1900
