This is a Remix of the Ultimate Spool Holder. I designed this to a clip version for the CTC Replicator. You can simply clip this holder on the left or right top of the printer case. The additional Clips (4pcs.) are for more stabillity.

Perhaps you have to fit the clips a bit. Use pressure, sand it or just cale it 1% bigger. For me, a bit pressure works fine.
