This little piece is used to adjust the left side of your Monoprice Select Mini x-axis endstop switch. I created this because I noticed that the MPSM has a print area of 120mm, but the bed itself is 130mm. With this stop in place, the prints are now centered in the build plate, instead of lined up on the left side.

I am using a glass bed that need clips to hold it tight to the metal bed, and this allows me to place the clips on the side and not have them knocked off when the prime blob is created.

There are two parameters, one for thickness around the support that this sets on, and the other is the distance that the x-axis stop is adjusted. I built with a 4-mm adjustment, which doesn't quite center the build, but moves it over enough for the bed clips.

How I Designed This

This took about 20 seconds in OpenSCAD.
