Monoprice Select Mini v2 Control Panel Relocation

thingiverse

This is a supplement for Monoprice Select Mini Panel Relocation for y'all MPSM V2 fans out there. I loved the design but wanted to add in the touch screen for OctoScreen, and along the way, discovered the box for the printer's LCD panel wasn't correct for my MPSM V2. The other tweaks I made were thinner walls (only 2mm instead of 3.25, should be fine), and I made them deeper than the original to provide space for my favorite spool holder. Things to Print: In general, follow the directions from Monoprice Select Mini Panel Relocation, except replace the LCD box with the MPSM LCD Box from this project. Use the one with a top if you don't have a second LCD. Use the one without a top if you do. If you have a second LCD, print the Pi LCD Box and Support. If your MPSM is going to eat your Pi (get it? It'll have Pi inside?), then print the Pi Mount, the Mounting Bracket, the Voltage Regulator Box, and the Voltage Regulator Box Top. The reason the Mounting Bracket has a second set of connectors is that it's an iteration of the bracket that holds my bed heater's MOSFET but now has to hold both. Other Things You'll Need: 1. A couple more M3 screws, some ~6mm, some ~12mm. The 6mm ones are preferably countersunk but they're inside the box so who's going to know. 2. Some way to connect the screen to your Pi. I used this cable but ended up detaching and reattaching the male end of it a couple times, and I'm no longer sure if it was necessary or not. Things You'll Probably Want, If You Want to Do This All with One Raspberry Pi Inside the MPSM: 1. A voltage regulator that can take the 12v mains in the MPSM and convert it into 5v 3A to power the Pi. 2. A short usb cable for connecting the Pi to the MPSM. Things I Assume You Already Have: 1. A Monoprice Select Mini v2 2. A raspberry pi running octoprint and/or octoscreen 3. A screen for the Pi like this one 4. A wanton disregard for what other people consider reasonable You can find more info on this in this reddit thread. Additional Notes: 1. I had to extend the cable for the MPSMs controller by splicing in some extra wire. It was a super tight fit otherwise, and I like having some room to spare when putting everything together. 2. If you want to do anything else with the Pi, you may want a GPIO expansion board because the IDE cable will eat all of your GPIO pins, even though the screen only requires 26 and actually uses even fewer.
