Easy to print – no supports needed and no additional parts required. It's fully 3D printable.

There are two versions available:

• With an integrated central axle – faster to print and more solid.
• With a separate central axle – a good option if you want to replace it with an M4 screw.

I personally use the version with the integrated axle, and it hasn't broken – not even once.

Easy to assemble:

To secure the pin-locking clip in place, I recommend using an empty .38/.357 shell casing.

It works great with PLA (though it may be a bit stiff to lock/unlock at first, it softens after a few uses).
