I stated back in 2020 – at about the same time I started my leather hobby – It was a Covid Hobby.
I had an Ender 3, but it was S.L.O.W. and really thought 3D Printing was nothing more than a novelty. Then I stumbled onto the 3D Printing sub-reddit and stumbled onto Bambulabs and their P1S printers – Everything just started to take off from there. There were so many tools that I wanted for leather that I was able to somewhat replicate using 3D Printers. The stitching pony, tool holders, jigs, you name it – I fell in love with it.
Then I found a way to marry it to leather as support for handles, little things here and there. It seriously comes in clutch sometimes. I still can’t figure out the stamps like you did, but getting there 😀
