Title: KeyCap Stem
Post by: Gassed on Mon, 21 January 2019, 12:20:12
Hello Everyone,
I think I got the Cherry Mx Stem right but I was wondering if someone could check my dimensions before i send it to my friend to get 3d printed. [attachimg=1]
Thanks for the help

You can make the blades the same thickness so that if someone mounts the key "sideways" it won't split the stem.

As to your measurements, the blades are 4.1mm long, not 4.

Good luck!

That would be 1.15mm thickness in both directions, right?

No, the blades should both be the larger thickness so that mounting the cap sideways doesn't crack the stem (forcing a 1.35mm switch stem into a 1.15mm keycap stem is a bad idea). Remember, this is the design for the keycap stem, so it just has to accommodate the largest dimensions possible which allows you to "cheat" and make the blades the same thickness.

I misunderstood, I thought they were making a custom slider for some reason. Thanks for clarifying.

I would definitely do 1.35 on all blades to avoid accidentally breaking stems.
