Useful STLs to Download

A collection of STLs I’ve made for 3D printing to enhance your fucking machine and bondage experiences. Nothing fancy, just useful bits and pieces.

Safety Locking Pin for Steel Bondage Cuffs and Frames

I find the tiny screws that come with steel cuffs on this locking frame to be incredibly fiddly to remove. Of course, that might be what you’re going for, but if you have a particularly tight collar and you’re playing rough, sometimes you need something easier to remove at speed. Since I couldn’t find any ready-made locking pins in the right size, I designed these. They fit all the way through, though you might need to push a little harder through the smaller rear section.

Note: if your steel cuffs have an actual key, this won’t work. It’s only for those that use a small screw and hex tool.

Screw-in Clip and Stabilizer for 25mm Pipe (Handy for Padding / Rests)

For padded arm, leg, and chest rests placed onto a 25mm steel bondage frame, these clips are screwed into the base, then simply push-fit onto the pipe.

There are stabilisers on both sides that allow it to rest flat, or can be ignored for a chest plate.

Hismith Leg Clamp

With tall legs and heavy dildos, the Hismith Premium can tend to “walk” around at higher speeds. Use these leg clamps with a sheet of OSB or scrap wood to screw them down. With a large enough piece of wood, you also something to attach tie-downs to and make an impromptu bondage fuck bench.

Leave the rubber feet on your machine, and the height of these allows you to still adjust the middle upright leg. I use PETG for added rigidity, but given the orientation they’re printed, I don’t think PLA would be an issue either — just be sure to use the “strength” profile for your print settings.
