Printed mine in ABS with 3 walls and 20% infill, but I'm sure PLA and less infill would work just fine.
I used these keycaps https://www.printables.com/model/399607-complete-cherry-mx-stem-keycap-set-optimized-for-3
Edit:
Added V2 with slimmer walls and base (all 1mm thick)
NO Supports. Support structures are built in to minimize overhangs for the switch plate on both models.
