<p>I've designed this for a 3D Printing enclosure controller I'm building using a Raspberry Pi 4.</p><h4>Design Features</h4><ul><li>1.6mm thick walls for sturdy construction</li><li>4 x 11mm knockouts for panel mount DC barrel jacks</li><li>4 x 6mm knockouts for panel mount 3.5mm jacks</li><li>3 x 20mm x 3mm slots for ribbon cables or other wires.</li><li>Mounting posts for M2.5 brass inserts for Raspberry Pi 4</li><li>Mounting post for DC-DC converter if you wish to power the Pi via GPIO (best to add protection circuitry if you do)</li><li>Mounting posts for M2.5/M3 bass inserts to support other components</li><li>Lid secured via M3 bolt into M3 brass insert on base.</li></ul><h4><strong>Printing</strong></h4><p>Suggest using PETG, not sure how well PLA would hold up over time.</p><ul><li><strong>Main Body</strong>:<ul><li>Material: PETG Prusament Anthracite Grey</li><li>Print Settings (PrusaSlicer): 0.20mm Quality, 15% infill</li><li>Supports: None</li></ul></li><li><strong>Lid</strong>:<ul><li>Material: PETG Prusament Anthracite Grey</li><li>Print Settings (PrusaSlicer): 0.20mm Quality, 15% infill</li><li>Positioning: Print the lid top side down.</li><li>Supports: Ideally paint on some supports for the small lips that lock into the base. Or select support on build plate only.</li></ul></li></ul><h4><strong>Hardware</strong></h4><ul><li><a href="https://amzn.to/32mLZH6">Raspberry Pi 4</a></li><li>12/24V to 5V DC-DC Converter:<ul><li><a href="https://amzn.to/3EAHHIW">10A (50W) version</a></li><li><a href="https://amzn.to/3EwhN9s">3A (15W) version</a></li></ul></li><li><a href="https://amzn.to/3FswtHP">2.5mm DC Barrel sockets and jack plugs</a></li><li><a href="https://amzn.to/3py4cu2">3.5mm 3 pole chassis socket and 3.5mm 3 pole plugs</a></li><li><a href="https://amzn.to/3sShR19">3.5mm 4 pole chassis socket</a> and <a href="https://amzn.to/3sDMHug">3.5mm 4 pole plugs</a> (these connectors may require the holes to be enlarged slightly).</li><li><a href="https://amzn.to/32EcGGG">M2.5 Brass inserts</a></li><li><a href="https://amzn.to/3EzqiAt">M2.5 x 5mm bolts</a> (for Pi)</li><li><a href="https://amzn.to/3z3WTx7">M3 Brass inserts</a></li><li>M3 x 8mm bolt (for lid)</li><li>M3 x 4mm for DC-DC Converter and other mounting points</li></ul><h5>Additional Notes</h5><p>This is my original design taking some inspiration from <a href="https://www.prusaprinters.org/prints/79181-compact-fysetc-spider-and-rpi-4-case-and-120mm-fan">Dan Andersen's Compact Fysetc Spider and RPI 4 Case and 120mm Fan</a>&nbsp;<br>&nbsp;</p><p><strong>Version History</strong></p><ul><li>V11 - Initial Release</li><li>V13 - Fixed gap between case wall and mounting bolt area. Smaller knockouts now 6mm, increased spacing between smaller and larger knockouts.</li></ul>
