Ball Stretcher, leash clip, tie point.

thingiverse

Simple and elegant device which locks around the base of the balls holding them firmly and providing loops to connect a leash, straps or weights to if desired. Easy and quick to print, no supports required. You'll need two of whichever ring you choose plus two of the retaining catches. The two pieces simply push together around your sack, once the small locating pins are in place slide the outer piece into the groove and click the pins into place. A small gap has been provided to help you remove it when required, if you don't have strong fingernails this may require a small flat screwdriver or similar. Once attached it will hold very firmly, be warned that excess force applied could seriously hurt or damage your body - tying it to something and falling over for example could cause horrible injuries. Always use safely and at your own risk. The basic version is great for holding the balls stretched while being as small and discrete as possible. Closing the legs fully is possible, though when the balls are between the thighs it makes it a delightfully uncomfortable experience. The balls are held tight providing a perfect target for little slaps, flicks, fired rubber bands, dripped wax, and similar. There are several ways to use the looped version, a leash can be attached to one of the clips or various strings and chains can be used to attach the leash to both, to hang objects from, fasten in bondage, or provide an easy to grasp handle. A string passing over the balls will help keep the device in place by separating them and pushing them outwards, this can greatly reduce the chance of the balls managing to get free - though this is only like to happen when relaxed and one ball can rise above the other making room for the lower one to slip through. There's also a version with a larger string hole, great for slightly larger clips or cords. Note - the version with loops has more rounded corners than the basic version, you may find this more comfortable. I'd like to make more options for this, such as an attachment that allows a crushing force to be applied when a string is pulled - ideal for carrying weight. Would love to hear any other ideas and requests. I'm not sure if I'd be allowed to link to images of a practical demonstration but message me and I'll send you the link via pm.
