Hi, I needed to bring some filament onto AMS compatible spools, I've seen excellent projects around but too complex and expensive, I don't want to waste filament, time and money buying bearings, screws or anything else.

Simplifying as much as possible and without needing anything else apart from a printer, I designed this. Simplicity is fundamental for me! you can use the crank, or a screwdriver on the removable pin.

WARNING: for the unwinding spool I use an open filament dryer, otherwise print the parts 2 times to have a complete set

If you are interested feel free to bring updates, I left

consider this alternative with AMS Lite: AMS Lite Spool Winder by B-Lab 3D - MakerWorld

HAPPY PRINTING EVERYONE :D
