Ender 3 v2 Hidden OctoPi Mount
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
<body>The tool-drawer holder in the Ender 3 v2 is the perfect place for a Raspberry Pi running OctoPrint’s OctoPi (big shout outs to Gina Häußge and Guy Sheffer). Just screw the RasPi to frame, plug in the connectors and slide it into the printer.</body>
##Design features##
+ Compact and tidy Raspberry Pi mounts for three different Pi’s
+ Active 30mm fan, 40mm fan, and passively cooled versions
+ Push-fits into the drawer shelf of the Ender 3 v2
+ Does not require any modifications to the printer
+ Easy tool-less access from the front
+ Big openings for airflow and wiring
+ Allows finger access to micro-SD card and camera connector while mounted on the frame
+ Big build-plate contact minimizes warping
+ Prints without supports
+ Looks like it’s meant to be there ;-)
<body>There are three frames, one each for the RasPi 1, Raspi 2, 3 & 4 (and 5), and the RasPi Zero 2W. The (ancient) RasPi 1 has two diagonal mounting holes, the 2, 3, 4 and 5 have four identically spaced mounting holes, and the Zero 2W has four tightly spaced ones.<br /><br />
Additionally, there are three “flavors” of each frame: to fit a 30mm fan (7-12mm thick), a 40mm fan (preferably 10mm thick i.e., a 4010), and a fan-less version. The latter works fine as the workload on the processor is minimal: the hottest part of the Pi is the USB controller which has never exceeded 60C/140F so far (see IR pictures). The fan-less version can also be used with Pi-integrated cooling solutions.<br /><br />
5V fans which…
