MMU2S Tube Guide 20200222

prusaprinters

<p>A guide for 5 x 4mm OD tubes spaced 15mm apart. Top and bottom half bolt together. The guide has countersunk holes for screwing (lightly, these are not built for strength) to vertical surfaces if required. Tested in PETG 0.15 layer height and PLA 0.2 layer height (0.15 will work as well). I have relaxed the bolt and hole threads; these may fail with more than finger tight forces.</p> <h3>Print instructions</h3><p>Prints without supports smooth faces down. I suggest 0.4 nozzle and a layer height of 0.15 to preserve thread profile. I print stock settings apart from Vertical shell perimeters 3. I do not consider publicly sharing GCODE files currently safe or useful so I have not shared them. Print times:</p> <ul> <li>0.15 layer height about 1:39</li> <li>0.20 layer height about 1:20</li> </ul>
