"Swedish" Style Locking BDSM Collar

Inspired by the stylish BDSM collars made by Swedish Collar, this is my take on a 3d printed locking collarFeatures:The collar is not perfectly round, but oval, with the larger dimension front/back. This matches the real shape of our necks, giving the wearer more comfort while still allowing the collar to be snug, especially when viewed head on.The locking mechanism (a padlock) is hidden into the sliding front plate, giving it a smooth, attractive look while still being fully functional. The padlock is fully optional, the collar functions just fine without it, minus the locking feature.The inner edges are beveled for comfort.The collar comes pre-sliced in 18 sizes, ensuring a great fit for anyone.The design prints easy, requires only small supports, and all sizes will fit on the A1 mini and up.Revised with the help of @Darktex to get a better sliding action, and more secure fit.
