Filament rewinder

thingiverse

I'm designing an extension for Mega Anti-Tangle Spool Holder, found here - https://www.thingiverse.com/thing:2479238. I had a run-in with a 2kg filament spool that was too large for my printer, so I rewound part of it onto some old 0.5kg spools, but the experience was a real challenge. This extension is optimized to work seamlessly with high-torque motors like this one - https://tinyurl.com/y5vynevg, and powered by H0 electric train power supplies for precise RPM control.
