I made keycap with a nearest exit sign, which I use for the escape key, since that's what it literally illustrates.
IMPORTANT: Since my keyboard has keycaps with the profile called DSA, this keycap is also using the DSA profile. You can read further in this article: https://teksbit.com/keycap-profiles-guide/#Types_of_Keycap_Profiles
I made an model of the exit-sign in Fusion360, which I merged with a keycap by using the OpenSCAD-library that I have marked this keycap as a remix of.
There is extra support under the stem and around the stem of the model included with the print profile.
I have also included a version of the keycap without the extra support as an stl-file.
