Maxkeys will print anything you want on their keycaps so I decided to try it out. I made the layout in Illustrator using their template and created the symbols myself.
It cost $35 and took about 10 days to arrive.
If I had to do it over I'd probably make the symbols a little thicker, but I'm pretty happy with this look overall.
If only Maxkeys offered other keycap profiles and a PBT option!
P.S. There is a flaw on the legend of the left shift (it should have the same symbol as the right shift) so I asked them if they can fix it.
