I was asked to make a kydex like printable sheet for my karambit. You can print it with fuzzy skin for a bit of a texture and it has a built in support so it can be printed standing up and then you can relatively easily break it off. I spould still print it with a skirt like 10 loops and 2 layers height will do.
I spend a few days on it. Karambit itself is uploaded to MakerWorld if you want to print it:
