Design considerations for perfect 24/7 butt plug
We have tried all major brands and their best products.
Implicit Creations and Njoy are pretty much the only ones that are comfortable enough for permanent use, but both are unavailable in larger versions. So we got a 3D printer and started testing various shapes and materials. The most important points:
- Oval shape, at least for the base. A round base can never fit well between your butt cheeks
- Material just barely harder than the body. So that muscles can still flex and it can be squeezed through narrow bone structures, that are spoiling the fun for some unfortunate individuals.
- The shaft has to be a little bit longer than usually expected. Because the butt hole doesn't work like a camera aperture, but more like a 4 to 7 cm tunnel.
- No pointy tip, because how can something pointy ever be comfortable
- No sharp corners but steep angles for the shaft-top and shaft-base transitions, so that there can be no danger of slipping in neither direction
- A coaxial hole is great for letting air escape, when that is acceptable. But it should come with a sealing plug for going out.
- Certain shapes can put pressure on the perineum and cause groin numbness, mostly in male users. With the coaxial hole design that is unlikely to happen, because the top part is ring-shaped which doesn't leave a lot of surface area.
- The whole design should incorporate or at least allow for an overall bend, because anatomy. Google 'how to poop like a samurai'
- Directly 3D printing flexible materials is possible, but creates an open porous media, that cannot be kept clean.
- Unless some very expensive technology is used, a 3D negative mould and pourable 2 component silicone has yielded the best results
- There are harmful substances in many silicone products, so a food or even medical grade silicone should be used
We'll test our design for a little while and then maybe set up an etsy store for it, if there is any interest. We are not looking to get rich, but we are full of ideas for other kinky engineering challenges that would benefit from another better 3D printer.
