Locking Bondage Collar

A shameless rip-off of the "Swedish Collar" style bondage collar. It uses a sliding face plate to hold the collar closed. The face plate can be printed so the collar locks closed, and requires a special tool to unlock. It makes a very satisfying "click" when it closes! You can also print a version that does not lock, but what fun is that? The collar inside dimensions are 148 x 120 mm, 34 mm tall. There is also a matching wrist/ankle cuff at https://www.thingiverse.com/thing:6927211.

I have also uploaded an alternate version of this collar, that uses magnets for the lock and key. Search for "BDSM collar with magnetic key"
