Broke or lost the tiny collet that holds the PTFE tube into your HGX Lite? Fear not, this will replace it. This is modeled to be an exact size and shape replica of the original, but printed in TPU. You can reuse the existing grub screw, or if you lost that too an M3x6 with exactly one washer is a perfect stand-in. It should print out fine in either vertical orientation. The tube retention with the screw in is actually pretty good. It'll come out if you yank it straight up with some force, but otherwise stays put.
