Smoother Tolerance Nut (Spool Fastener) for Universal Auto-Rewind Spool Holder

thingiverse

This is a remix of the "Flat" style nut from the Popular Universal Spool Auto-Rewinder. This helps fasten the spool in place onto the hub. When I first tried printing the 3 stock files, none of them threaded very smoothly. If you have a look at the pictures, you can see exactly why. There was a extremely fine/small tolerance on the original model which even the best printers will struggle to reproduce properly. This remix solves this issue by adding a 0.5mm tolerance to the section sizes of both the Male and Female threads. After performing a fairly quick n' dirty test print, the new nut screwed in perfectly to the hub. I didn't need to file anything down or man-handle it to get it on. Nice and simple installation. If you like this design, be sure to leave a comment and a like. Thank you! "Bark bark!" RoscoeTheDog
