My polyamid filament spool warped a “little” after the semi-professional dehydration process in my kitchen oven. It didn't fit on the normal spool holders of my machine anymore.
I designed this spool roller/holder to use such deformed rolls (see picture or video).
The base_part and the top_part are connected with an axial bearing. [51103;(17x30x9mm)]
The upper and lower part of the bearing are press-fitted into the printed parts and the ball cage lays inbetween.
The holder/roller has really low profile and is strong af.
Comparable bearings have a dynamic load rating of 11.4kN (1.162,48 kg)
and a limit speed of 12.000rpm.
I tested the assembled system with 150kg and 180rmp → the roller just laughed at me.
The upper part is designed to fit spools with ID of 50mm perfectly.
Other spools, with ID up to 90mm can also be placed accurate using the 4 concentric circles.
(60, 70, 80 and 90mm)
The lower part is designed to use as less material as possible while providing the needed stength and sexappeal.
I printed the parts in CF-PLA at 0.2mm layer height with a 0.6mm nozzle == extrusion width.
For the top_part I used very dense supports to asure a good bottom surface quality.
