Universal Filament Spool Holder but better by mvorn44

Last crawled date: 3 years ago

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
