Kailh Choc Calculator (Button) Style Key Caps

This is a remix of my other design, the key caps made after Olivetti Praxis.
While they were working, they were not as comfortable as I wanted. The rectangular shape was punishing my finger tips when the finger approached the key from any angle but perpendicular.
Been happy with my other board with ALPS keys and calculator-style tops (of my own design too) I decided it was worth a try to put a similar set of caps on my ThumbsUp! v10 keyboard.
The result is here.

As usual, these caps don't need support and the pair of keys should be printed with the slot on the connector/pins pointing upwards.
The model was created for 0.3 layer height, 0.4 nozzle, no support, the rest is as you wish.
