Description
I designed this keycap using OpenSCAD. I obtained the dimensions directly from the Cherry MX developer support page: Developer Page - CherryMX. The dimensions don't match the actual dimensions that I measured with a caliper on a switch but it is because of a protrusion along the edges of the vertical cross section. I used the specs from the developer page and then added a bit of tolerance.

I typically print keycaps with the text/value facing down on the heat bed because I use the textured sheet (with PETG) and I like the texture that it imparts on the keys. In this case, the heart is a fairly large opening and I am not sure that I like seeing the shape of the filament in the heart opening (it is a bridging area) so I tried printing face up with “Hilbert Curve” as the top fill pattern and I am very pleased with the results. In the macro pad picture, the top one was printed face down and the bottom one was printed face up.
I tested the model with PETG but PLA should work too.
