LDSA keycap profile

LDSA is a new Choc-compatible low-pro keycap profile by Darryl from – with deeper dishes.

Darryl, designer of the Corne-ish Zen keyboard, announced his idea of a new keycap profile in January. His plan was essentially a low profile version of the DSA keycap (or uniform MT3): a spherical and uniform profile with deepened scoop and lengthened skirt "as much as possible."

I want to produce something that is comfortable to type on, and looks a bit more traditional – Darryl.

According to Darryl, the dishes on these are deeper than any other commercially available keycap. And the finger pad that your finger touches is larger than that of MT3 and SA.

Actually, the dishes are close to the deep dish homing keys of MT3 caps: 1.52mm vs 1.63mm.

Not going for a sculpted ergo set makes it easy to put these keycaps on any obscure physical layout.

Despite the deeper dish, LDSA (blue) is not much thicker compared to MBK (red). Otherwise they are identical in width and height so they fit Choc-spaced (17x18mm) PCBs:

LDSA seems much larger because the skirt is 1.35mm longer. Definitely taller by a little bit, but probably only like half a mm – Darryl.

The molds and the first sample caps are ready, so after the initial renders there are already real comparison photos available, e.g. this one with a lonely MBK lost in the sea of freshly arrived LDSAs (click to enlarge):

How to grab those? Stay tuned for the upcoming presale which is slated to start April 24. They will be available at and can be shipped internationally. Edit: Here you go.

Doing a little presale in a week or two for cheap to get the profile out there and see if people like it enough to go dual shot – Darryl.

Until then, here are some STLs if you want to print the caps and see if you like this profile. License reminder: these files are released under the Creative Commons, non-commercial license.

  • They will be available in all black or all white PBT
  • They are choc sized (17x18mm)
  • They are a deep scoop keycap, similar in feel to the MT3 and SA homing dishes
  • They have a longer skirt to hide the switches more (compared to MBK and MCC)
  • They have slightly longer legs to allow for o-ring use and still allowing firm grip on the stem (compared to MBK and MCC)
