MendelMax Filament Guides & Guide Wheel & spool holder

prusaprinters

<p>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.</p> <p>All guides are designed for 3mm filament. The rotating guide wheel would work for 1.75mm filament as well.</p> <p>The side-mount spool holder should work with most filament spools.</p> <p>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</p> <h3>Print instructions</h3><h3>Category: 3D Printer Accessories Instructions</h3> <p>The rotating upper filament guide wheel needs the following "vitamins" to build:<br/> -2x M8 x 30mm SHCS<br/> -2x M8 nut<br/> -~4x M8 washers<br/> -4x 608 bearings</p> <p>You'll need to print 2x of the wheels.</p> <p>I'd recommend that you place 3-4 washers between the two bearings in each of the wheels, so when you tighten the M8 screw it doesn't apply a side-load to the bearings and bind them up.</p> <p>The lower filament guide requires 2x 608 bearings, and 3x M8x30mm SHCS. The holes are sized to tap the holes and not use a nut on the back.</p> <p>All other parts are self-explanatory.</p>
