Ender 5 - Additional electronics plate - with Raspberry Pi by rmpel

Last crawled date: 3 years, 1 month ago

A buck-converter mounting plate that screws to the PSU of the Ender 5, and catches behind the power-switch for stability.
I designed it to mount 2 of the LM2596 modules with voltage display (see image) and a Raspberry Pi.
Hardware requirements; some nuts and screws, nothing special. You could use a tap for and screw in m4 bolts, but for something electrical, I prefer to use a nut to make sure the screws stay fixed :)
The bolts that fix the plate to the PSU should be M4x8, no longer. The plate is 3mm thick at that point on purpose; the PSU has 5mm thread (as described in the spec sheet), so M4x8 will be safe. There MIGHT be more room inside, but I have not opened my PSU to check. Leave a comment if you know more than I do ;)
The Raspberry Pi mounts under an angle. This is not harmful at all, but if you are not careful, you might accidentally short the GPIO pins on the case. I strategically stuck a bit of electrical tape on the case to prevent shorts.
One could, of course, design and print a GPIO cover that would insulate it ... New project idea :P
Hardware list
2x M4x8 for mounting the plate to the PSU
12x M3 nut
12x M3x5 for mounting the buck converters and RasPi to the mount.
Warning!
The raspi has M2.5 holes, just ease (and I do mean EASE) the M3 bolt in one turn in, half-a-turn back, then undo and repeat 2 more times.
This will slowly widen the mount holes. It's fine, just do it really, really carefully.
