Old Town PDL drive plug print in FLEXIBLE

thingiverse

If printed in TPU (or other flexible), this is virtually unbreakable. TPU melts/fuses itself so completely... well, IYKYK! No O-ring: the O-ring s a great idea with hard plastic because of expansion/contraction. But it is not necessary with an all-rubber (TPU) part.This design is VERY SNUG with my print setup (x-y compensation set to -.05 and extrusion multiplier at 1.0 using a generic flexible filament). You may need to print it at 98% or 101% size. Don't give up. You. Can. Do it! hahaThere is a slight bell shape (0.6mm) on the wall which wedges it into the tube. I smacked mine in with a hammer head.Get it started and place wood or a hard cover book on it, then give it a whack with something. It is not going to walk away, very tight!FWIW my TPU prints at 230CI used 3 walls (0.3 nozzle but 0.4 is great, only 2 walls if 0.5 or 0.6) with 4 bottom and top layersGood luck if you are trying TPU without direct drive! It will work... just SLOW it down. I am printing at 30 but without direct, I might slow it to 10 or 15.Fell free to print as many as you want to give away to friends, but no resales please!Happy Yakkin' to you!
