I made a leather stamp out of delrin and it worked really well. in the example above I should have run the laser a second time to get a deeper etch. All you need is your vector file and a piece of delrin. In fact I have a piece of this in my bin you can have. I think it’s 1.25 inches wide if that’ll work for you. My bin looks like this.
I can’t help onsite but I can give you my notes on how I made mine if it helps.
