Recently the controller board on my Monoprice Select Mini (MPSM) v2 3D printer cooked some of the motor controllers and the heater MOSFET chip. Looking online I found the board listed on the suppliers website, but as well as being out of stock it was a little expensive and would have to be posted from the Far East to the UK for an extra fee. So, deciding not to wait for them to come back into stock (if ever they would), and in order to save some money, I decided to replace it with a Makerbase Robin MKS board with their LCD touchscreen.
Wiring the board into the printer was relatively straightforward: most cables just plugged right in, with just a couple needing cutting and stripping to go into screw terminals. However, the display is a different size to the old one so to get the printer looking good I decided to design a fascia to hold the new LCD display. And of course that provided an excuse to add a full-size SD card socket to make it easy to access memory cards (a bit of a design flaw for the stock MPSM v2 as it's at the bottom of the side panel and being micro-sized is fiddly to get out or in).
The design of the LCD display means that the fascia needs to be bolted (with M3 bolts) to the 3D printer front casing and the dislay then screwed onto it from inside the casing. That last bit is fiddly, but I managed it fairly easily with a short screwdriver. The positions of the screw upstands makes it quite easy to use some washers to clamp the display on. For the SD card socket I bought a short SD extension cable that has a sort-of-SD-card one end and an SD card socket on the other. To hold the socket in the fascia I designed a small bracket that can be glued in for the socket to be screwed to.
A small issue with this project is that the fascia is too big to be printed on an MPSM v2, so I included a version cut in half with overlaps so that the two pieces can be carefully glued together. That's the way I did my fascia and as the photos show it turned out quite well after some filling at the joints and spray painting.
Of course, you may find your display or SD socket are a little different to mine, or even you may want to make a custom version of the fascia, so the OpenSCAD file is also included here.
