Single sided spool holder Heavy Duty

thingiverse

The finalisation stages of my Lack enclosure required a suitable deck mounted spool holder. I wanted it fixed down to prevent it sliding off when the cover was removed or fitted. I also wanted something that was quick and easy to operate so decided on a single sided mount with a quick thread nut and bolt which is fairly typical. The holder itself is probably hopelessly over-engineered but I figured I'm only going to make one or two of these and want it to last without snapping or bending. It is intended to utilise the standard Anet spool holder shaft and the supplied nuts and washers from the original kit. The M8 threaded bar is screwed into the threaded hole of the mount for around 35mm (40mm deep blind hole in model). A lock nut and washer is then tightened against the face to prevent it unscrewing. The spool bolt is slid onto the threaded bar and secured with either a nyloc nut, or a pair of the supplied nuts locked together. The spool bolt is designed to utilise a pair of the standard 608 bearing, to ensure free running on the spindle. I have designed the spool bolt and nut to accommodate every spool I've experienced here. These are Prima, Sunlu and Rigidink plus a few cheapo bucket examples which I probably wouldn't buy again. Spool widths of 55mm - 75mm and boss diameters of 52- 75mm.
