Rollers and Filament guide for Formbot/Vivedino printers stock spool holder

I quickly became frustrated with the stock spool holder on the Forbot/Vivedino Raptor 2 needing to adjust it constantly for different size spools of filament.

So with a few minutes in Fusion360 and a couple revisions we have a set of rollers that fit snugly over the bearings of the stock spool holder and a filament guide that slides snugly into the slot on the stock uprights.

This set up works great up to about 450mm Z height prints, anything above that and you need to remove the filament guide.
