BIBO 3D Printer Spool Carousel Holder

This is a replacement to the standard "kitchen unit leg" spool holders for the BIBO Intouch 3D Printer. It utilises 42x3x7mm ring bearings, significantly decreasing spool inertia.

Requires 2x 6806 2RS 42x30x7mm bearings - https://www.ebay.co.uk/itm/223058142582 (select 42x30x7mm).

Printed on BIBO and fits most 1Kg spools with circa 52mm diameter hole and circa 62mm wide. Please note, however, that it doesn't fit some larger spools that are circa 80mm wide but with a small hole (e.g. PRIMA brand).

A small amount of sanding may be required to fit the spindle through the bearings but don't over do it as it requires an interference fit to hold the bearing.
