spool holder roller with cone-shaped bolt-head and nut to center and fix the roll on the spool. There is also a “built in” function that enables adjustment of friction in the roll by tightening or loosening the outer screw. inspired by the spacer mod: https://www.printables.com/model/941785-sv08-spool-holder-spacer-mod

it uses the original parts from sv08 as much as possible. replaces the roller and end-cap only.

the shorter one works for 750g spools (54mm wide spools) with a inner diameter hole up to 65mm. it also uses only sv08 parts, so it s easy to install.

the larger version supports wider spools, same inner diameter (without adapter). but it needs a printed axle with heatset inserts for the screws. i tried to use the same size inserts as sv08 original axle, but i felt that they were to big, so i used m3 5x4 inserts instead.
