The file 'Poor Mans Ender 7 Bed Noise Stabilizer 3D Printer Model' is (stl) file type, size is 11.0KB.
This is a very rough first attempt at stabilizing the Ender-7 bed without a fancy triple-lead screw.
Just secure it to the column, and put a spring between it and the bed (like in photo).
As for my tests, this reduces the shakiness by a good amount.
