How can one have a custom keycap set built?
By custom keycaps I mean keycaps with a custom geometry that doesn't exactly match the profile/shape/size of any existing keycap set.
I'm currently 3D printing such keycaps but I wonder how they could be built in (non-3D-printed) ABS or PBT.

The shape is not too exotic; they look kinda like this: https://adafruit.com/product/5111 but with some (nontrivial) differences.

Bonus question: how to add custom art/fonts/icons to the keycaps.

If you have to ask, it's too expensive. You're looking for a set of 100+ custom molds to be created for your unique keycap set. If you want doubleshot keycaps, it doubles the number of custom molds. You would be requesting a keycap manufacture to create brand new molds for for the profile you desire, plus the R&D of mold making. Unless you plan to sell your own keycaps using your unique profile, it would be cost prohibitive. I would expect no less than 10k and likely north of 15k for a one off, custom profile, injected keycap set.

With a few hundred to thousands of hours of work and access to a small desktop mill you could replicate what this user did and cast their own keycaps using lego and plastic/silicone molds.

Woah, I am confirmed vendor- Very cool thank you no style

And another one of these: https://shopgoodwill.com/item/199032147

im currently using the akko 5075 b-plus dracula with ks3 milky pro yellows and this thing is super buttery with xda caps. my only issue is the rubber feet keep coming off when im pushing on the board. next keyboards gotta be a heavier one tho 100%

coin mod lmao

assetto corsa no hesi has become soo addicting so run, been on it for a while and also been looking for a good steering wheel to use. does anyone have any good options? another good racing game ive recently been enjoying is night runners, its pretty much assetto but retro vibes.

i have a fanatec csl elite. cant comment on value for dollar since my uncle gave it to me for free but its really good, super smooth cuz direct drive as opposed to the cheaper logitech wheel (that my uncle also gave me lmao) but the logitech wheel is good if u dont wanna spend a lot. anyways i usually get advice from sim racing discord servers there are some really friendly and helpful ones out there

just so u know though night-runners doesn't support wheel, and i believe wheel support isn't planned either so far.
