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.

Building the rCrumbl the Ultimate RaspberryPi Phone

About a year ago I set out to create a functional smartphone from a Raspberry Pi. Its been a fun adventure. I began this project with only a moderate amount of experience in working with electronics, and I’ve come a long way since that time. I am by no means the first person to create a raspberry pi phone there are one or two people who I am certain have come before me. In order to claim some sort of title for the work that I would be doing, I decided that I would attempt to create the smallest form factor phone possible given my knowledge and experience. This alone became quite the challege, but in the process I learned a great deal about product design, CAD, and 3D printing.

Cooling Fan Wiring Update – Essential Monoprice Mini Mods

After printing out a couple of benchmarks with the upgraded carriage and cooling fan modification I’d noticed that overhangs facing away from the printer were not what I was hoping they would be. I suspected a first candidate for fixing the problem would be to pull the small circuit board out of the fan shroud. I had initially hoped that the board would be tucked away and small enough to not impact print quality; I was wrong. The problem became where to put the board. I was not interested in a complete rewire of the project so I needed a better solution.

Half of an hour in CAD and this is what I came up with. I’d always planned on putting a small fan shroud on each of the cooling fans, why not integrate a small space for the circuit board to tuck it all away? Perhaps I’ll add space for a small button to control the fan without unplugging it. You can download it here free of charge!

Carriage Upgrade and Cooling Fan Wiring- Essential Monoprice Mini Mods

Over the past several months I’ve been working with the Monoprice Select Mini V2 it is a solid printer right out of the box especially for the price. Despite all of the amazing things about this printer, it does come with a couple of small flaws, many of which can be fixed for pennies with a simple print and some cheap hardware. Today I’m looking at the E3Dv6 carriage upgrade by US Water Rockets. As a bonus I’ve included a short guide on how to effectively wire the LED and part cooling fan that is meant to be attached to this modification.

I’d had my eye on this upgrade soon after picking up this printer. I’d noticed that the stock carriage for the E3Dv6 style extruder that comes with the printer causes the gantry to tilt ever so slightly forwards as the center of gravity is quite far away from the linear rails. Additionally, printing calibration cubes demonstrated that the printer had a fair amount of play in the x axis. Initially in order to fix this I had printed some belt tensioners also designed by US Water Rockets. However, this carriage design improves the belt tensioning system dramatically by integrating it directly into the carriage.

This upgrade was also an opportunity to upgrade the stock plastic GT2 pulleys with full metal ones (Shout out to spool3d.ca). The part cooling fan is the only part of this print where I could see there being room for improvement, the rest of this upgrade is rock solid and really made a measurable improvement in the printer’s accuracy.
