Rollin on 20s Filament Roller

*** Check out Version 2.0 over here... http://www.thingiverse.com/thing:1687448\nI liked the holder but needed a few changes. It required extra hardware and had multiple pieces. I fixed that by modifying the bearing axles with a mushroomed head and a split down the middle, so a bearing can be popped on without additional hardware.\nI also modified the frame mount for 20mm aluminum frames, adding a tiny bulge to grab onto the center channel. They snap into place perfectly, providing resistance but still adjusting to width.\nTwo of these and four 608 skateboard bearings get you a completely adjustable filament roller that sits on top of your favorite aluminum-extrusion-frame printer.\nUPDATE: After maxing out my Z, I realized the X carriage would interfere with these mounts. It's not a problem unless printing something over 180-190mm tall. Check it.\nPrint Details\nPrinter Type:\nRepRap\nPrinter Model:\nHICTOP Prusa Mendel i3\nRafts:\nNo\nSupports:\nNo\nResolution:\n.25mm layers\nInfill:\n20% Slic3r Honeycomb\nDesign Process\nImported original STL to Sketchup, modified, and exported back to STL.
