Filament Hub

This is a Filament Hub to provide a surface for some filament spools to ride on. I printed the Spool Holder with bearings from T_B_A (https://www.thingiverse.com/thing:3646853) which works great, but some of the filament rolls I have don't ride on the bearings well.

Specifically I was trying to use the new Duramic cardboard filament rolls and the cardboard was grinding into my holder, so this is my solution.

The 55mm hub sits really well with the Duramic cardboard spool, and I also created a 52mm hub as some of my spools center diameter is just under 53mm, I haven't tested the 52mm one on a spool yet as its printing as I write this..

Good luck and enjoy
