MP Select Mini 1.65mm Z Spacer (No Disassembly Needed!)

thingiverse

This customized spacer clicks neatly onto the Monoprice Select Mini's z block. Since I'm using the 'Monoprice Select Mini spool holder' by Toys, which clamps around the outside of the printer, I couldn't use the original version with levers. The clamps interfered with them, so I removed the levers and turned one 90 degrees, centering it with additional support added. Additionally, I noted that the Z limit switch is offset from the end of the inside gantry block, so I added a small 'paddle' to the bottom arm and a clip to the inside of the top arm to keep the offset correct. This style of spacer has several benefits: it allows for easy insertion and removal without disassembling the machine, features no overhangs, and requires no supports at all!

From the rear, slip the hook side of the spacer with the 'paddle' at the bottom through the gap in the tower and click it into place on the side of the z axis block. Use a thin stick (tongue depressor, small screwdriver, chopstick, etc...) to push the levers through the front gap and ensure they've clicked in, then pull on the tab to secure it. Install your glass bed and re-level as necessary. Design Process Remixed original model in Tinkercad, with clean-up done in Blender.
