Is anyone interested in making internal details?

I'm remaking my ages (actually 1 year) old craft, Eridanus MPCV. This is what I've done.

Since it would be armed with some Vizzy codes, I'd like to focus on making Vizzy. However, as you can find out, this craft currently has no furniture inside. This looks so bad. So, I'd like to outsource the furniture.

Making Furniture

The capsule has 2 layers: One is outer panel and the other is pressure vessel. Your primary goal is filling the pressure vessel with proper structures. Pressure Vessel is a 3.65m wide cabin.

I'd appreciate your every potential effort, but there's some requirement:
- The entire capsule shouldn't be heavier than 8.5t. This means you have 500kg spare. You can use Tinker Panel to make your furniture mass 0kg tho.
- The capsule's CoM shouldn't be off too much. I would fine tune it afterward, but too much offset would make it impossible.
- It should have 4 seats.
- The more it look real, the more I'll be happier.

Whoever you did, I'll show you my genuine appreciation. If your work is finally chosen to my selection, I'll credit your name whenever I post this craft.

Thanks in advance!
