Filament spool hub


Just a simple mod to help the filament spool roll. Some of the spools have a large center hole, hang with an offset and the filament needs to tug more to get it to roll. Of course you can print a hub but it turns out peanut butter jar lids are a close match (I taped some and sanded others to fit). For the Ender 3, a 1 1/2" hole saw gets it over the spool support end. The lids even have a center divot to center your hole saw. Use a lid on each side
