120mm base, round lip

120mm round base, round lip. I've attatched a version with 1mm and one with 2mm depth for base structure (high and low version).
In addition I've added both versions with a 0.5mm phase, the easiest way on your FDM printer to avoid small elephant foot.

Edit(18.09.2022): Added two new stl files with 2.5mm deep base, steeper roundlip like original bases!
