Ender 3 V2 Raspberry Pi 3 Case Mount

thingiverse

First off, this more or less a 'remix'... But typing the Thing ID in search on the 'This is a Remix Option' brought nothing up? So I couldn't select anything... So, I got the base model from here: https://www.thingiverse.com/thing:1956623 Who apparently remixed this: https://www.thingiverse.com/thing:922740 Who in turn remixed this: https://www.thingiverse.com/thing:608169 And so on... I moved the Raspberry Pi logo down a little, covered the unrequired port holes and added a double rail slot mount, strongly supported underneath. The idea behind this case it to attached to the back left of an Ender 3 v2, having the wires to the Pi (ethernet and USB) entering neatly at the back out of sight rather than the front. This does mean you're hiding the micro USB power port as that will now be at the rail side, so the power for this is via the GPIO pins and powered by the printer itself... There is a small hole in the bottom section of the case to put the wires through. You'll notice in the photo's I've made a narrow hole in the top case for the Pi camera module ribbon cable to go. I've now made this hole shorter than the photo shows, as it unnecessarily long. The print does require supports but is quite straight-ford, nothing special to be aware of. I will mention one thing though for anyone wondering... Why would you power the raspberry Pi case from the printer itself? Why go through the trouble of opening up the PSU cover and adding a buck converter and messing around with wires? Also, when the printer is turned off, then there's no power to the raspberry pi.. So you then can't use the Pi itself to remote power on and off the printer (if you wanted to, through OctoPrint and a Wifi plug for example). I don't know is why! I guess it was just a neater way of doing things? I was going to change the whole setup so that I could have the OctoPi print server always on, but then I decided not to bother, it's not like I'm going to be starting a print while I'm not at home, that would just be bordering on daftness, so I left it, and it does look neater...
