Atari 600XL key replacement

I had to create a completely missing Atari 600XL keyboard key. The key is a variant of discontinued Cherry M8. For the key cap I used Parametric Cherry MX model. The spring is from this button. It's not perfect but it kind of works...
Here are keycaps parameters:

[ // 13 - Atari 600XL Profile
18.16, // Bottom Key Width
18.16, // Bottom Key Height
5.40, // Top Key Width Difference 5.3
4.60, // Top Key Height Difference 4.7
8.2, // total Depth 8.2
2, // Top Tilt 3
1.8, // Top Skew
//Dish Profile
3, // Dish Type
0, // Dish Depth
0, // Dish Skew X
0 // DIsh Skew Y
