Monoprice Select Mini Z Carriage

thingiverse

I purchased a V2 mini off of eBay as a parts printer. After a few repairs, it's performing like new, however the x-axis end stop switch post was damaged on the original carriage. I also discovered that the mount for the lead screw is integrated into the carriage design, making it impossible to add a Nema 17 motor without replacing the entire carriage. This helped me in both areas. I'm not the original designer, but rather modified the design to suit my preferences. I added an end stop switch bracket, reduced the length of one side to accommodate standard 35mm bearings, enlarged the bearing holes and reinforced the mounting plates for the Nema 17 motor and lead screw nut. The original design was two-piece, whereas mine is now a single piece. You can view the original design here: https://www.myminifactory.com/object/replacement-z-axis-assembly-for-monoprice-select-mini-v1-52822 I printed this model using PETG with 100% infill for added structural integrity. Update 11/14/18: I've since created a second Z carriage, tailored specifically to the V2 mini, and it's oriented correctly for printing. My initial design was remixed due to misaligned bearing holes. With access to the original working file, I was able to correct this issue with ease. The new model also allows users to secure X-axis rods using M3 nuts and bolts instead of glue. Additionally, the integrated x-axis switch is now removable, eliminating that noisy X-axis cover.
