this is a i think better redesign of my other ratcheting design. you just slide end of tube into slot in roller and wind. an arrow on rod shows direction to wind. the ratchet design will hold tube from unwinding as the tube rests against the frame. the roller just slides and snaps in an out of the frame when needed to assemble or remove tube. supports needed on roller. i made removable spacers, which keep the roller from separating during print. i did this to prevent having to use supports all the way up the inside. saving 15 mins print time. the frame need a cpl supports on the inside of the ratcheting area. chamfered the wheel to make it more comfortable turning.
