Started Printing 2018 with Mk3. NOT an engineer or programmer or technician (I'm a business/ management/ finance guy) but love boardgames and this is a tool to help me make games even better. I'll do the occasional functional print, too. Mk3 (not S or anything else) finally had hot-end die in 2025. Got Elegoo Centauri Carbon to get an enclosed printer and will upgrade/fix the mk3 to an S or S+ and give to my son in engineering school.
