Spool Rewinder

thingiverse

You'll want a simple spool rewinder to make switching between filament spools straightforward. The design self-tightens when using a drill, which keeps the plastic safe from stripping out with an embedded nut - you'll only need a 1/4-20 tap for this operation. Make sure you follow these instructions carefully. First off, print the updated version of this design. This new edition comes without any pause to insert the essential part, so once it's done, all is good and well. On the other hand, those printing the third version need a 39.5mm pause right after finishing layer forty. Here you'll have time to put in the crucial nut; just wait for a moment then get going again as per normal operation requirements.
