Tbh I doubt I’d use it much I just like building stuff. Blah blah… Journey not destination…

I made a pen holder attachment for the same reason. A regular printer is way better at drawing a 2d image but it was fun to make.
But that’s good feedback thanks guys.
You can DIY apply solder mask and then mill out the pads, you can get special spring loaded bits that let it cut through the mask but not the copper if you want but at that point ordering them online is definitely the winner.
I saw someone use a etch resistant pen on a 3d printer and Ferric Chloride with fairly decent results but the lamination method definitely was faster and higher resolution.
