MendelMax Filament Guides & Guide Wheel & spool holder

Set of filament guides for a MendelMax printer. I have had all sorts of problems with filament tangling during printing, so I created these guides to eliminate any possible issues. It includes two options for the upper guide- one fixed curved guide, and one rotating wheel.
All guides are designed for 3mm filament. The rotating guide wheel would work for 1.75mm filament as well.
The side-mount spool holder should work with most filament spools.
1/1/2014 Update: Added dual wheel upper guide and dual bearing lower guide for even lower friction filament feeding- hopefully equaling better part print quality
