Shim to level print bed Free 3D print model

I came across a video on YouTube where a milling machine compensated for its own bed irregularities by precision-crafting a minute layer off the surface, and this innovative concept immediately sparked my interest as a potential solution for leveling cold bed printers. Unlike the traditional milling process, this counterintuitive approach should also be effective here. The fundamental principle is that as you print the shim, any discrepancies in height are evened out by the action of plastic not being forced down on low areas. As additional layers accumulate, gravity takes over to fill in the low spots, while compression firms up the higher regions. I estimate a shim height between 3-5mm should be sufficient to compensate for most minor unevenness. This is merely an exploratory idea that might aid me in reconstructing my printer, but it could hold merit. A simple design like the provided STL file can fit your bed dimensions without using up excessive plastic material. You may need to run some sandpaper over it to smooth out any raised areas from the printing process for the high spots.
