Humbler BDSM

thingiverse

This is a Humerus, a BDSM device designed to prevent a man from standing up. Perfect for petplay or other forms of BDSM/Bondage. The model measures 290mm across and comes in two halves, perfectly sliced for 3D printing, requiring no supports at all, although it's specifically with this model that elephant foot problems can be very tricky, so make sure to sand those areas away. Otherwise, the device should be usable directly after coming off the print bed. Hole dimensions: 22x20x60mm (enough for all ball sizes). This device requires 2 x M6 nuts and bolts (length: 45mm minimum) to function properly. The two halves can also be forced together by binding a rope through the holes, although it's recommended to use the bolts. The model features four additional holes for mounting cuffs or other items.
