Wall Mounted Spool Holder/Rail

thingiverse

I made this mount to fit a 20mm dowel. If its not obvious you'll need to print two, one for each end of the dowel. Bang some screws through the wholes and bosh, you have your self a nice sturdy wall mounted rail for your filaments. I've printed these on standard factory 0.4mm nozzle settings and with custom settings. I used 20% infill but have a play and figure out what's best for you.
