About this 3D model

Outer diameter of pipe (that goes through the spool): 50mm Diameter of ‘flower’ part that clips onto the spool: 95mm Height longest part: 70mm Inner diameter of tube (where bearing or desiccant goes): 40mm I think these BARELY fit into the bambu spools Designed to hold 1.5" ball bearings (I used these ; affiliate link) to weigh the cursed spools down in the ams. Or you could put a bunch of desiccant in. Whatever brings you joy… I use these mostly with zyltech spools. no idea what other ones they'd work with.
