Replicator 2X Filament Guide Holder

This simple filament guide holder solves the problem of filament wrapping itself around the spool holder and jamming as it feeds. Filament is now taken from the center of the reel instead of the side, and thus has a much easier time getting from the spool to the printer without jumping off the reel and going all horribly wrong. There's also a straighter path from the reel to the filament guide tubes, thus the design provides a considerable reduction in friction in the feed process.

This object is designed to snap onto the existing structure of the printer without interfering with the cables - simply secure it with four screws of your choice - I used some sheet metal screws I had lying around, but pretty much anything will do) and it'll work perfectly. It fits both the printer's structure and the filament guide tubes very, very tightly: once you insert the tubes (you'll need to use a twisting motion to do this, and it'll take a bit of persistence), you won't want to remove them again
