Works for Ender 3, Ender 3 pro and other printers that uses 40mm aluminium extrusions on the bottom.
I have designed Ender 3 anti vibration feets with stock bed springs. But it's a bit too wobbly so I decided to use Ender bed silicone pads witch I bought from aliexpress.
With this damper set the printer is lifted only about 30 mm from the ground. Useful for cleaning dust and filament under the printer.
I personally love this setup because printer is stable and nothing wobbles. Printing noise decreased considerably. Works perfect like it suposed.
