Multiple Mechanism Auto-Rewind Spool Holder (remixed print direction and track)

thingiverse

Update 04.03.2020: Updated Track and readjusted profile again. With this profile I'm not able to force a block under any circumstances. Included a version for the original Base and the modded base. The modded base is not necessarily required, just use the track that prints flat. <br> <b>All credits of the awesome design fly to ea69</b>, just remixed some parts: - the track: now prints the teeth in the "stronger" print direction. I did this because on some circumstances the rewind blocked if the the teeth of the gear have been exactly sitting on each other before the retract (rarely happens, but you can reproduce by manually moving it to this special position). I changed the first two teeth in size and shape to counter fight this. Therefore I wanted the "stronger" print direction for them. Unfortunately this also requires a new base. Frankly, I'm not sure if this is 100% solved, I could think of using sharp gears to address this fully but have not tested so far. - the base: required to fit the new track and also added a center hole for a single screw or an 8mm magnet
