<p>Prevent axle separation from bearings and gain space on your desk.</p> <h3>Print instructions</h3><h3>Category: 3D Printer Accessories Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2DxjZlB">i3 MK2 MMU</a></p> <p><strong>Rafts:</strong> Doesn't Matter</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0,2 mm</p> <p><strong>Infill:</strong> 20%</p> <p><strong>Notes:</strong></p> <p>I recommend a brim for the SpoolholderUpper.stl and SpoolholderLower.stl</p> <h3> Post-Printing</h3> <p><strong>Mounting the stand and back.</strong></p> <p>The SpoolholderStand and SpoolholderBack parts fit together by friction. I added 2 mm holes so you can secure the connection with tiny screws, if you want. Be careful when you stick together the stand and back parts, because the back part breaks easily.</p> <h3> How I Designed This</h3> <p><strong>The reason why I created this</strong></p> <p>The new MultiMaterial spool holders have a tendency on long prints to loose the axels from the bearings. So I designed the SpoolholderUpper.stl to prevent the separation. Then I realized that I can minimize the space, needed for the 4 spools, so I created the rack. You need 4x SpoolholderStand.stl and 2 x SpoolholderBack.stl and 8x SpoolholderUpper.stl and 8x SpoolholderLower.stl.</p> <p>I've included the SketchUp file, so you can improve on my design.</p> <p>Happy printing<br/> Andreas</p>
