Shim to level print bed

thingiverse

In a YouTube video, I discovered that a milling machine levels its own bed by removing a tiny layer from the surface. This concept could be useful for cold bed printing as well. The idea involves printing a shim to level out height differences by gravity's effect on low areas and compression on high areas. A 3-5mm high shim should suffice. Create a simple structure, sized for your print bed, using the provided STL file. Print it onto your lowest surface, keep it there with glass or another covering, and you'll have a perfectly leveled bed. The attached STL is 19cm x 19cm x 3mm in size, with an OBJ model included. However, if you can print this shim, your bed might already be relatively level.
