MP Select Mini Threaded Rod De-Wobbler Coupling

thingiverse

This replacement coupling connects the Z-Axis Stepper Motor to the Threaded Rod in the Monoprice Select Mini 3D printer, designed to replace the factory coupler that causes misalignment and introduces wobble into the Z motion. This leads to a banding effect in prints. To address alignment issues between the Threaded Rod and the Stepper Motor, I have included a Flex Coupler. The detailed instructions for this modification are documented in my Hack-A-Day Project Log: https://hackaday.io/project/14823-monoprice-select-mini-maximum-3d-printer-mods/log/51880-dont-go-wobbly-on-me-now Print Settings Printer: Monoprice Select Mini Rafts: No Supports: No Resolution: 0.04375mm Layer Height is best to get the threads nicely defined. Infill: 20% or more Notes: Use thick walls and thick top and bottom layers to make this a strong part, capable of withstanding the demands of 3D printing.
