Secret Weapon Miniatures has a Kickstarter going for a new line of modular rpg dungeon tiles that nearly slipped by me. With less than 2 weeks remaining this Kickstarter is blowing through its stretch goals and may very well be something that you might be interested in.
These tiles are going to be made out of PVC, light weight and more durable than resin...it has a lot to offer. Their choice of material is also why they have teamed up with Reaper, which has considerable experience with PVC. It also means that you have the opportunity to add on a significant number of Reaper minis and paints to your Kickstarter pledge.
Tablescape Dungeons looks like a very cool modular RPG dungeon set, be sure to let me know what you think in the comments!
