Not sure if stupid or genius, I realized with the mounted Filament Carousel by BensHacks I wasn't able to use the Sidewinders (not so good) spool roller contraption. After tinkering with bowden guidance and external holders I combined two nice things with these RollerClips. Mount filamentries "TUSH" onto the empty carousel and fix them with 4 of the Clips. Works quite well and keeps you flexible if using a MaserSpool or a traditional Spool.
