This SVG file goes with mcpea's 3D model of the printer made for PrusaSlicer, which although excellent was missing a proper build plate texture. More exactly, this file replaces the black build plate texture with the big white FLSUN logo provided in Art3Design's remix. Thanks to both of them for providing the basis for this work.

This version more closely matches the real look of the V400 golden PEI build plate. It is also made translucent and almost transparent, so that the FLSUN logo is not as prominent, and more importantly you can see in PrusaSlicer your 3D model to be printed through the build plate even when looking from below it.

To install this golden PEI texture in PrusaSlicer, go to:
Settings → Printer Settings → General → Bed shape → “Set…”
and load this SVG file (V400_PEI.svg) as the texture,
alongside the 3D file (V400_bed.stl) provided by mcpea, Art3Design or from here, as the model.
