Ball gag

Description:

Classic, notorious, known by all Ball gag, in three different sizes. 
Yes, I know, these days you can have one bought with your groceries. But when I was teenager, I couldnt buy one. No internets, parents looking over my shoulder all the day... and little money if any. In these days I would give much to have opportunity to just print such thing secretly over the night.
So... I dedicate this to all shy, BDSM-positive teenagers who cannot afford buy one for any reason. Enjoy, mates!

3D printing settings:

All the belts needs TPU or something similar. They have to be able to bend. 
The rings should be made from PETG.
The ball, and the pin can be printed with PLA or practically anything. I have used PETG, because I like PETG. Ball from any hard filament is hard (duh), uncomfortable and little bit torturing, which can be your desire. Speaking for myself - I like how it feels.

If you wanna try the ball from TPU to have softer one... well, I have tried without supports, and it didnt went well. But with supports it surely can be done. Never tried to do TPU with supports, but heard that they have tendency to stick with printed model. Nothing what sharp knife wouldnt solve, I think...

When assembling, turn the rings so the disconnected ends are hidden in the belts. No glue needed, all should fit nice and tightly.

Three sizes - D means diameter, number after this means... diameter (duh). In mm.

Nothing more to say, it is simple as it is.

P.S: If you already bought my previous gags, you can use the main belts and the rings too. Profit.

Update: I have added a slider. I personally dont think it is needed, but if you want to lock both belts together when using the gag, you can use that thing now.
