Keycap for keyboard Didaktik

This is a solution to the problem of the unavailability of wide keys for the "Kailh Chocolate V2 Low Profile Mechanical Keyboard Switch" buttons.
I described this project in the article https://sindik.at/?p=931138
Today, I solved this problem using 3D resin printing.

The key has the following dimensions: 28 x 18 x 8.7 mm
It is necessary to use resin printing with transparent resin.
I highly doubt that anyone could achieve the desired effect using an extruder.
