so a friend asked me for some custom rollers, so that they could roll them onto mugs they were making out of clay, took me a couple hours to figure out how to do it. but a hacky way to make basic ones. i printed proof of concept on an fdm, but likely going to design a few more, and print them all on a resin printer. if printing with fdm, might try flipping upside down, to reduce supports skull and crossbones. -tested with silly putty, and they work decently

i stole ideas from a lot of folks for this,

so i used this guys walk through on using the emboss tool in fusion 360 https://www.youtube.com/watch?v=aAjhTFxi2_w but i'm importing svg art to make the patterns (but watched a half dozen videos on how to do it and tried with blender)

i'm using a tool shape like streloch does here https://www.thingiverse.com/thing:3710446 but simplified because i was happy to just have the pattern on the outside.

pro tip on the skull and cross bones, print it upside down to not have to deal with supports (will update stl so it is like that natively)
