**Fat Spool** for Cetus3D is an adapter for the Cetus3D spool holder that attempts to minimize the rocking seen when using wider and heavier spools on smaller holders. Can also be printed **without supports**.
If this is your first print and you want to use less plastic, be sure you specifically disable supports in the Cetus software (it's enabled by default, find it under **Print->Preferences**). If you see a weird chunky wavy surface on your print, those are supports and they are totally fine (they just waste a bit of plastic for more printing stability). Just like the bed, you tear them off with the cutters once the print is done. Also be sure you re-enable supports for future prints, as not everything can be printed *without* supports.
It has effectively a 50mm diameter, and with the lip is designed to work as if it was 60mm, but it doesn't get stuck on 50mm spools. It's 80mm long (wide enough for a 70mm spool) and should clip on to any standard 20mm V-Rail with ease.
Tested to fit eSun, Polymaker, Boots Industries, Filaments.ca, and CreatorFuel filaments.
*Ahem*, this is a bit silly, but if you print it in white, it looks a bit like Onigiri. :)
