MPSM X-axis adjustable stop

thingiverse

This custom piece calibrates the left side of your Monoprice Select Mini's x-axis endstop switch to perfection. Having created this modification myself, I realized that the MPSM boasts a print area measuring 120mm in diameter, yet its bed size is slightly larger at 130mm. By incorporating this stop, prints now beautifully center on the build plate instead of haphazardly lining up along the left side. As a glass bed user who needs clips to secure it firmly against the metal base, I was frustrated by the constant threat of having them knocked off when the prime blob forms. This solution allows me to strategically place these clips on the side, ensuring they remain securely in position throughout the printing process. Two adjustable parameters give users complete control over this modification: one determines the thickness around the support that this piece sets for itself, while the other specifies how far to adjust the x-axis stop. I personally built my adjustment with a 4mm increase, which may not perfectly center the build but still effectively moves it enough to accommodate the bed clips.
