clay rollers for patterns

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

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
