About this model

Initial build is set up for 3/8" soft copper tubing, which was able to straighten very well from a coiled roll. Uses 5x 608RS generic cheap bearings and M8 hex bolts. Use long shank bolts between the top and base to maintain alignment. Printed in PLA for stiffness with 2mm floors and walls and 40% infill. I only ended up using the outer two through bolt holes. Bottom side of base is recessed for the hex heads. Could be used as a large radius bender by removing the outer 2 pulleys. I'll try and get some other diameter pulleys uploaded as well (5/16", 1/4", 3/16") Updade 2020-02-01: Added 3/16", 1/4", 4mm, 6mm, and 10mm pulley files
