Lack v2 Backside Vent

prusaprinters

<p>Backside Vent for Lack Enclosure v2 with MMU2s. Comes with holes for the filament tubes and two sliding doors for better ventilation when printing PLA. Opening is big enough to fit a hand through, so it's also good for simple backside maintenance work and dis-/connecting the PTFE tubes when combined with <a href="https://www.prusaprinters.org/prints/22339-prusa-mmu2s-rear-ptfe-holder">https://www.prusaprinters.org/prints/22339-prusa-mmu2s-rear-ptfe-holder</a> .</p> <h3>Print instructions</h3><p>I printed it with Prusament PETG to colormatch my printer, but any PLA should do. Tolerances are tight for snug fits, so printer should be well adjusted.</p> <p>Besides the printed parts you need a bit of super glue, 4x M3 nuts and 4x M3x10 screws.</p> <p>Mounting instructions:</p> <ol> <li><p>Remove the backside acrylic pane from the enclosure and put a square hole in it with a jigsaw or something similar, for dimensions see the picture. Doesn't have to be perfect, the parts will hide the cuts anyway.</p> </li> <li><p>Affix the outer panel with masking tape and drill the screw holes with a 3mm drill. You can drill right through the screw holes of the outer panel, no need to remove it.</p> </li> <li><p>Add the M3 nuts to the inner panel. Put a bit of masking tape on them if they tend to fall out. Turn the part around and lay the doors on top of it.</p> </li> <li><p>Put the parts together (inner panel and doors first, then acrylic pane and outer panel on top) and use the M3 screws to secure everything to the acrylic.</p> </li> </ol> <p>NOTE: If you're not used to handling a jigsaw or a drill get some help. Power tools don't discriminate between material and people when it comes to making cuts or holes. If you already assembled the Lack v2 without hurting yourself you should be fine though.</p>
