Filament Feed Tube Holder/Clamp for Maker Bot Replicator 2X

I don't know about everyone else, but the feed tubes on my Maker Bot Replicator 2X would constantly pop out. So I've created a simple and aesthetically pleasing clip-on clamp.

Both .thing files are ready to go, the "Tube Holder With DualX Letters" is a dual extrude print and will require a dual extruder printer. I also posted the STL files for the single extrude model.

Enjoy!
