Large spool holder for CR-10s

thingiverse

I had access to a large roll of PETG at work, so I needed a way to utilize this material effectively on my CR-10s. The existing options didn't meet my expectations, prompting me to create my own solution. To do that, I had to print three versions with the tabs pointing downward and one with the tab protruding from the side. This side tab allows for easy mounting to the top of the CR-10 control box using the stock filament holder bolt holes. I used standard skateboard bearings leftover from a fidget spinner project and some spare hardware lying around. The result is extremely robust, eliminating my concern about it splitting in half and dropping my roll mid-print, as I had feared with versions relying solely on being pressed into a bearing. This design was specifically tailored for 3.5 kg spools.
