Description
Unsure about the tube measurements? Check your dimensions with a 3D-printed plastic test tube!
We offer a service to 3D-print your tube in plastic before producing it in metal! The plastic model is not meant to be worn as a chastity belt, but is sturdy enough to be put on so you can check the dimensions. You may even use a belt and some string to simulate how the cage feels when held in place as in the real belt.
How to measure
Measure the length and diameter of your flaccid penis. A caliper works best to measure the diameter. The tube will be manufactured to this diameter, so make sure you can insert your penis (do not subtract from your measurement). Measure the length of your penis from the beginning of the shaft at the body to the tip in a straight line. The tube will be 1 cm shorter than this measurement to give a snug fit.
