filament spool winder.

use this to rewind tangled or badly rolled filament onto a new spool warning you use this at your own risk. you can change the size in the customizer for your required spool center hole. you have a choice between a full printed version with drill attachment if you choose this one please print it in abs or petg in 100% infill for extra strength or a hollow center hole verson will take 10mm screw thread bar and a nut on each side. theres also a wedge to insert into the end to keep the filament on the winder. id also use rubber tape or neoprene to prvent your spool from spinning around on the spool re winder.find it on ebay look for sticky back neoprene. the default size is pretty big meant for excelvan filament.good luck.
