Ender 3 Raspberry Pi case (buck convertor & 60mm fan)
Description
Did a little remix of this simple yet effective Rasbperry Pi Case for the original ender 3. Modifications: - thickened the walls for greater strength - added m3 screw holes for the lm2596 and shifted one of the holes by 1mm so that the screw would face it - made a bigger hole for the raspberry pi ports (still compatible with the 3 but also the 4, haven't tested the 5 but it should be ok) - made a few improvements make printing the thing easier - added holes to allow a 60mm fan to be screwed into the dedicated slot on the top This design will allow you to power the raspberry pi from the printer PSU, have it cooled, all in a pretty small & solid box with not so many cables. For that you will need: - this 3d printer model (oc) - usb-C cable to scrap (or cables large enough to powerthe raspberry pi, personally my dupont cables were too thin not to throttle the pi) - 2 cables (I got one with a fuse) to give power to the lm2596 - 2 large terminal connects (probably 20A or 30A ones, I had pretty large ones but I don't know exactly what size they are) - 20cm XT60 cable M-F - 60mm (x10mm height max) fan - a bunch of m3 screws (at least 2 ~6mm for the lm2596 & 2 ~12-16mm + 2 bolts for the fan) - 2 (at least) small screws to screw in the raspberry pi - raspberry pi (+mini usb cable & sd card) - lm2596 Note on pictures: The version I have on my ender 3 and which is on pictures is an old one, I made some holes with a driller, ... I reworked the model to avoid having to do that
