A Quiet Enclosure for the Monoprice Select Mini

After moving the MPSM to the bedroom adjacent to ours, it became impossible to print while sleeping, it just made too much noise. I decided it was high time I came up with an enclosure for the machine. Luckily I had all of the tools and hardware I needed. I just needed to get my hands on a piece of plywood from Home Hardware. I grabbed a nice 4×8 sheet of project panel which was more than enough for this cabinet. I wanted to make sure that there was plenty of space below to store any extra pieces of hardware or tools and that there was plenty of lighting to ensure that I could see what was happening in the cabinet.

I started by producing a rough wooden box with the plywood. Unfortunately I didn’t have access to the table saw at the time, so I was stuck using the circular saw. It was nothing that a quick pass with the belt sander couldn’t handle (Thanks Peterborough Tool Library!). The door was quickly cut with a jigsaw and attached using some cheap hinges from the hardware store.  I also cut two holes in the back to place some fans for controlled ventilation.

The electronics all came together smoothly, and I even had most of the parts I needed lying around. I used a small 12v 5a power supply for the LEDs and the fans. It was all wired together using a small piece of breadboard and controlled by some red push buttons I had lying around. All of the electronics fit in a small space in the base of the cabinet.

I wanted it to be very bright inside the cabinet, so I painted the inside with some high gloss white paint. I stained the outside of the cabinet with some oil. I even had some helpers come by for this part of the project! After it had all dried, I placed the electronics back in place and reattached the hardware. I used a small piece of 1/8 inch glass attached with some hardware corner brackets printed on the 3D printer. The extra space in the bottom also houses a raspberry pi that I run octoprint on.


With the printer in place it is time for a test print. Next up I would like to run my webcam into the enclosure to be able to monitor my prints remotely. I’ll keep you updated with some slick videos produced in the cube!
