40mm cooling fan mount for Einsy Rambo with Raspberry Pi Zero 2

prusaprinters

<p>Been noticing my Raspberry Pi Zero 2 isn't happy when I am printing in an enclosure as it gets a bit warm. &nbsp;It idles around 55 C so needed cooling is needed. &nbsp;Decided to make an easy enclosure that doesn't rework the factory setup too much. &nbsp;</p><p>Designed fan to be centered on the Einsy Rambo plane so that air is split between cooling the front of the board and the back where the RPi Zero 2 is.</p><p>Designed to use M3x6mm screws to hold the cover to the base. &nbsp;Screws will need to cut into the PETG, no nut holders in this first version (Note v2 has been uploaded, provides spaces for M3 hex nuts. &nbsp;Cover holes may need to be drilled out with a 3mm bit to make threading easier. &nbsp;M3 bolts and nuts should be used to hold the fan in place.</p><p>Looking at using a power cords splitter and USB adapter to power a USB fan with speed controls to simplify install.</p><p>&nbsp;</p><p>Pictures to come once I have mine printed and installed.</p><p>Standard Prusa settings for the Einsy box recommended (PETG etc). &nbsp;Print the lid the same, but make sure the flat side is down on the bed.</p>
