Filament Spool Rewinder

Updated on February 7, 2026

Thank you everyone for the likes and downloads Currently, about 5% of users have reported that the nut is difficult to screw So I specifically modified the print profile and reprinted it with the following changes

1. The nut's XY dimensions are scaled to 101% and text has been marked on the bottom surface I personally tested it and even slightly damp or expanded filament can be screwed in smoothly

2. Infill changed to 20% cubic As long as the hex wrench is inserted it will not affect the thread strength

Note If the 101% scaled nut is still difficult to use please adjust the nut's XY scaling individually in your slicer software Scale by 0.3% each time do not move the Z-axis

A convenient electric Filament Spool Rewinder supporting 1kg filament spool (approx 73mm inner diameter, approx 60mm thickness) and 200g trial filament spool (approx 50mm inner diameter, approx 23mm thickness)

Filament tangled Is the remaining 1kg filament taking up too much space and hard to organize This electric Filament Spool Rewinder can solve both issues

I prefer to wind the remaining 1kg filament onto a 200g filament spool to save space

Hex wrench pass-through and embedded design no need to worry about breakage due to low print strength If the thread breaks a hex wrench can also be used to unscrew the broken part

It is recommended to add a print modifier to the threaded area to reinforce the infill and walls

Usage requires an 8mm hex wrench (medium size, 160mm long) to be clamped by a hand drill
