Over the summer, I found some tops from my kid's fruit pouches that looked really interesting for a piece of terrain. I saved three that I could find and held onto them. We also had some spice containers in long, thin vials.
These two combined with some plastic styrene and I will have three chambers. Looking at some images, these chambers should be roughly 2 inches tall.
I think these will be fun objectives for UEDF defend missions and/or Zent capture and escort missions.
Here are photos of materials and screen captures of the chamber in case anyone else is interested in making some of their own.
When I am able to get these built, I'll add more photos to this thread.
Caps (These will be the base of the chamber)
Spice Vials (very similar to what I have. These fit well over the cap and will have cover with styrene)
