This is a design that's used to wrap your wired headphones up to keep them from getting tangled if my students will use them, LOL!  Stick the plug end in the mouth or tail end then wrap until you get it to the end or beginning and stick the ends in the other hole.

These could be printed in PLA, PLA+, PETG, PETC, ASA, ABS, Nylon, etc.  The ones in the pictures are done in Overture PETG on my Snapmaker U1 with BIQU Glacier plate!

Post a make if you like it and get some pts!!! :)
