Rewinder tools to assist with (re)winding spools.

Designed to print flat with no supports and no cleanup required. Base cone fits snugly onto the threaded shaft. Hex end allows using a drill to help wind the spool. Clearances are set very tight, you may need to adjust the size very slightly depending on your printer.

Small rewinder can fit spools with opening from 7mm to 24mm. Spool height depends on inner diameter, up to 50mm. Useful for small spools like solder.

Large rewinder can fit spools with opening from about 19mm up to 90mm. Screw length is about 90mm. Should be useful for re-spooling filament from damaged or non-confirming spools.

Note: Sizes were chosen to suit a specific need. If they are not right for you, send me a message and I'll post new ones.
