Auto-Rewind Spool Holder for Anet A8

thingiverse

These parts (and a 200-mm M8 rod) will put an auto-rewind spoolholder on your A8. This will maintain tension on retract so that your filament spools won't get tangled. See the original thing for the auto-rewind bits you'll need to complete this. (Use one of the SpringRound_* springs; the tab will engage with the lock block.) You'll also need a 200-mm M8 rod, as the 150-mm rod that's part of the A8's stock spoolholder isn't quite long enough. (175 mm would work too, if you can get it at a good price.) Two 608ZZ bearings are also needed. You could also just use the spoolholder by itself...but where's the fun in that? The design is similar in concept to https://www.thingiverse.com/thing:2141857, but it is an original, from-scratch design.
