Universal Filament Spool Holder but better
thingiverse
My attempt to improve the design. Uses a slip nut and locking nut. The Support Plate was designed for this specific arm. https://smile.amazon.com/dp/B07Z756H2X?psc=1&ref=ppx_yo2_dt_b_product_details The Support Plate is sandwiched between 2 Fender washers. Makes a very strong and secure attachment. See pics. The Slip Nut slips over the threads but doesn't rotate. There is a keying feature that locks into the groove that is cut into the threads of the Spool Holder. Parts Needed: 5/16 x 5.5" Fully threaded Bolt (M8 is an option) 2x 5/16 nut (M8 is an option) 2x skate board ball bearing 608ZZ 8mm (core) 22mm (outer diameter) 7mm (width) 2x 1.5" Diameter Fender Washer
