Monoprice Select Mini X Axis Stabilizer

thingiverse

My Monoprice Select mini V2 was plagued by a rattling noise that grew especially loud during circular movements. Upon closer inspection, I observed the thin metal frame on the X-axis arm vibrating in resonance. Seeking to resolve this issue, I applied a piece of tape tightly to the arm and took note of its effect (see attached picture). With some success, I decided to create a more permanent solution. The first design consists of a small square piece that fits neatly into the cutout area and presses upward/downward on the sheet metal frame. While this brought some relief from the rattling noise, I felt it was worth exploring further options. I then created a second version - a longer piece designed to press gently onto the sheet metal frame. This design closely mimics the effect of applying tape tightly across the metal. For my purposes, this second iteration proved more effective in reducing the noise level. However, due to the asymmetrical cutout on the arm, this "device" can only be attached one way. Note: At this point, I have been experimenting with 3D printing for about a month and this is my second uploaded creation.
