Penis Scrotum Splint
Two acrylic plates are connected at the top with a hinge and separated by two 50mm screws at the bottom of the device. The back plate has a hole for putting the cock and balls through. Wing-nuts are used on the screws to bring the plates closer together. You can tighten the crusher all the way, making the open space only 25mm wide. Or you can make the space almost 50mm wide (the length of the screws) for a lighter crushing.
Both clear acrylic plates are 120mm across and 170mm long.
Diameter of small hole: 38mm
Diameter of big hole: 50mm
