I liked the design from the original model, but the mesh was poor resulting in an unattractive print.
Found the original image online, and remade the extruded version from scratch using the image as a canvas.
Included a version similar to the original and one with a rectangular backplate.
Recommend scaling the model X and Y at least 125% while keeping Z at 100% (4mm).
Example picture is printed in PLA:
X and Y scaled 125%
0.4mm nozzle
0.2mm layer height
10% gyroid infill
2 walls
3 top layers
pause at start of layer 11 (2.2mm) - Print with black first, switch to white during the pause.
The author remixed this model.
Remade the model from scratch using the same original 2D design.
