Interlocking hexagon wall mount with keyring insert. Interlocks will need to be adhered to each other in some way. The keychain only uses 4 hex to attach, pictured is the dimensions needed to make your own inserts. Happy printing :)
Notes:
3/18/2022-Found out the insert was to long. It has been fixed and reuploaded. If you have downloaded it before this date please redownload.
If you are printing on a Mini/Mini+, the skirt edge distance needs o be set to 1mm instead of 2mm to fit on the bed.
