One of my year 10 students gave me a gift voucher for HeroForge after I helped her print her miniatures and inspired me to start painting and 3D printing my own. This led to terrain and I'm currently using this as an opportunity to get back into Blender and designing for 3D print.
My miniatures all ended up with a CyberPunk style so the terrain is following suit and I'm putting the results up here to track progress. Hopefully others get some enjoyment from all of this and offer further ideas and feedback.
