Great idea! Very similar to your AB walls. Easy to make a much larger village with a few buildings and a set of walls. You should bundle.
I wish I could cast things as quickly as you, although I can already see myself getting carried away. My wife would probably yell at me for spending hundreds of dollars in resin!
I could have used those walls for my Mos Eisley set up!
Maybe if I wait long enough you’ll start making 15mm sci fi. I only have to wait 10 years!
