65mm Spool Holder - CKC28 Special Edition

This is my very special model of a spool holder for the most common 65mm spool size that ships with the 1 kg / 2.2 Lb filament quantity. It can accommodate actual spool widths of 60 to 70mm, and can be used for warped, lopsided or otherwise untrue spools. It works with the standard skate bearing (8mm ID, 22mm OD, 7mm thick).

There are hundreds of spool holder designs currently on thingiverse and at first I thought to use an existing design rather than make my own. I tried a couple, but had issues with tight clearances that were incompatible with warped spools, excessive sanding and or modding to get parts to fit and extra fasteners needed for assembly. So, I decided to design my own. I hope it works for you. Better still - I hope you try it, hate it, and decide to design one of your own. The cycle continues!
