MeanWell PSU and PI box

<p>Upgraded Micromake D1 printer with Klipper/Fluidd and wanted to streamline all the parts and cables so built a combined PSU/PI box that has the UBEC internal feeding the PI directly on the PI header pins. &nbsp;Now there is just the AC, USB, and the power cables external and routed neatly outside. &nbsp;</p><p>Update: Added mounts for normal mounting and BMG extruder style.</p><p>I use 2 banana clips for the 12v to the printer and a combined switch plug in. &nbsp;I use banana clips because i can always plug more stuff into them if I want to add lights… etc.</p><p>Power Plug - <a href="https://www.aliexpress.com/item/32802260124.html">https://www.aliexpress.com/item/32802260124.html</a><br>UBEC - <a href="https://www.aliexpress.com/item/32723077">https://www.aliexpress.com/item/32723077</a> (I did not use a ferrite)<br>2x M4 ~ 10mm screws to attach PSU bracket<br>3x M3 ~ 15mm screws to attache PSU cover.
