Horizontal Spool Holder

This is a lazy-susan style spool holder. I made it for my Fabrikator Mini which does not have a spool holder.

It uses 28 3/8" ball bearings (slingshot ammo). The base, top, and hub are held together by a 1/4"-20 screw. I used a nylock nut to prevent it from loosening when turning.

Print both the base and top so that the bearing groove is facing up for the smoothest channel.

I have included two different adapters for different size spools which just slide over the hub. The 55 mm adapter fits ESUN spools. The 51 mm adapter fits Matterhackers and Ultimaker spools. I haven't tested any others. You can make your own adapters for different spools.
