This would've been super useful when I had a cartridge stuck in my hotend. I had to pound it out with a punch, marred up the hotend pretty good.

Sorry the bunnies didn't have it out in time to help you.

Bunnies have make it even worse because they follow the PC overclocking edict of metal-metal contact >> thin compound layer >>> thick compound layer.

To get tighter metal contact, they add a 0.003 inch thick brass shim to make the fit more snug. Boron nitride still coats all the surfaces, but the goal was to force the contact on the inner side to be as tight as possible. The extra tight fit makes the heater cartridge a bit more difficult to remove. After four scary reassemblies, it was time for a jig.

Not sure if you're aware but Slice has an alternative design for this kind of tool on their website.

Regardless, welcome addition. Thanks!

I made a bearing press tool for the B04 motor blate but you revised and made it obsolete before I could even publish it. LOL!

No. Didn't realize they have a tool on their website.

Sorry you wasted your effort on making a tool. Bunnies added their tool about the same time the bearing mounts got improved for easier pressing. The current motor plate design's mounting holes are much easier to press into.
