<p>Inspired by <a href="https://www.prusaprinters.org/prints/31482-raspberry-pi3a-mount-for-prusa-mk3mk3s">xiphmont's</a> implementation, I created my own files for the enclosure and pi3a+ frame for this update. &nbsp;Please follow xiphmont's &nbsp;guide to install the pi3a+ and perform the upgrade. &nbsp;The installation was flawless for me with the included octoprint image. &nbsp;Xiphmont's original cover file is included for completeness.</p><p>I had some issues printing the pi3a+ spacer frame and had to simplify it. &nbsp;The many holes for the keepouts on the Einsy board had a problem sticking to the textured sheet.&nbsp; I also optimized wall thicknesses and features to work well with the Prusa printer part settings.&nbsp;</p><p>The pi3a+ frame and Einsy housing has routing support for a 16mm wide FFC cable to connect a pi camera to the on-board connector. &nbsp;The frame also has a bit of clearance for the hex key to access the top mounting screw.</p><p>I have this upgrade implemented on two MK3S+ printers and the pi's with connected camera run without any issues. &nbsp;A world of difference from the ZeroW.</p><h4><strong>An installation point of note:</strong></h4><p>Slightly bend the FFC cable after plugging into the pi, away from the HDMI connector, about 20° and no more. &nbsp;You will crack traces if you bend it at 90°. &nbsp;The slight bend will help it to naturally seat in the right direction during install. &nbsp;There's a ramp in the frame that will also guide it but it needs a bit of help.</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/70609/rich_content/2d423f36-ced9-4315-bbfc-03188cf83970/image.png#%7B%22uuid%22%3A%2262921a91-f0f0-4448-b487-01fbf7466d74%22%2C%22w%22%3A862%2C%22h%22%3A552%7D"></figure><p>&nbsp;</p><h4>Design Screenshots:</h4><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/70609/rich_content/0d40aba7-3d7c-4381-b1d7-fcd9ea05b5c4/image.png#%7B%22uuid%22%3A%22f86a84f5-c91e-4233-916b-ff12cf8ff15c%22%2C%22w%22%3A1720%2C%22h%22%3A977%7D"></figure><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/70609/rich_content/86aca1ee-03fd-4ac0-a725-0116f884f6d3/image.png#%7B%22uuid%22%3A%229e9d4d73-c830-4151-93d2-a678f601aac5%22%2C%22w%22%3A1826%2C%22h%22%3A996%7D"></figure><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/70609/rich_content/87bfe549-3855-47f1-b314-3ff59f22bcfc/image.png#%7B%22uuid%22%3A%223717bf7c-b444-4802-a3d3-34f61c715c09%22%2C%22w%22%3A863%2C%22h%22%3A1205%7D"></figure><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/70609/rich_content/90b2222a-e77c-4cec-be71-2b0e9e770893/image.png#%7B%22uuid%22%3A%229752c3f5-e66c-4562-986e-6f642f57acaa%22%2C%22w%22%3A1199%2C%22h%22%3A1062%7D"></figure><p>&nbsp;</p>
