Clip to hold second filament out of the way on Replicator 2I like having 2 spools mounted on my Rep2 at the same time to make filament swapping easier. DON'T USE PNEUMATIC TUBING, it has too much friction. Use a stiff plastic. Unfortunately, there's no way to keep the second tube/filament out of the way during printing.......... Until now. I simply used the existing bolts on the Rep2 to attach a binder clip to the side. This clip can keep the unused filament properly spooled and tucked out of the way during printing. No downloads, just get a small binder clip.
