Prusa i3 Bed Stabilizer

thingiverse

Undeniably, there are solid reasons why my Prusa i3's heated bed is stabilized by three closely positioned linear bearings. This design results in a harmonic frequency that activates at specific points when moving the bed along the Y-axis, causing an intermittent buzz/hum that affects print quality. To mitigate this issue, I attached a pair of 'things' to the rear of the bed, resting on the Y-axis rails (notched side towards rail). This modification significantly reduces the buzz/hum and enhances print quality, but may limit the full range of the Y-axis movement.
