I had bought one of the X1/P1 PTFE 4-in-1 Adapters to retire the old splitter I had, and was a bit surprised to see how tiny the release rings were for it. There are a few tools out here but they were either complicated, only fit the A1 version, or tiny little things that I know I'd be dropping behind my printer.

So… I made one that fits over my thumb instead.

This makes it easy to index either as a thumb ring or as a push tool with your fingers. I tested it on the 4-in-1 adapter, a Hub, and a Buffer - all worked fine. I also printed it in both PETG and PLA just for giggles and both came out nicely (the PETG profile is basically just slowed down a bit).

Includes two little detents for 6x2 magnets to stick it somewhere out of the way. You don't have to add these, but it's a tight fit that I just press-fit in with some parallel pliers.

While using it this way you can use your fingers to support the back of the adapter to push back if you need to, while your other hand handles the actual PTFE tube itself.
