Ender 3 Rear Case

prusaprinters

<p>This is my design for a case for the mainboard of an ender 3 (ender 3/pro/v2). It was created with an SKR e3 v3 in mind, but should work easily with a stock board.</p><p>Needed:</p><p>6 x 4mm threaded M3 inserts (I used <a href="https://www.amazon.co.uk/gp/product/B08H563S9W/">these</a> )</p><p>6 x 8mm M3 screws (can reuse ones from original mainboard case)</p><p>There is room for a 40x20mm fan, I'm using a noctua 4020 but other brands should fit. There is also 2 little pegs next to the fan enclosure to hold a buck converter if one is needed for the fan.</p><p>I've tried to add as much room as possible to route cables, while still ensuring it will fit under the Y axis arm, and the bed spring cogs won't catch on any cables.</p><p>once you've got your cables sorted, the lid slides on, and then the entire thing slides back.</p><p>When printing, supports are only needed on the right-hand section that fits into the 4040 rail. (and possibly the fan cover, if you struggle with bridging)</p>
