Small Bunker or Guard Shack

This is version 2 of my 3x3 bunker. I'm still new to designing gaming pieces so please, if you have any suggestions, leave a comment.

I added a lot more detail to my previous version.

This link has all the parts I've made so far. I'll be adding more as I think of them. You can copy these to your own Tinkercad creation and make your own. Just be sure to set the grid to inches. https://www.tinkercad.com/things/b6f3TkCntdk-building-parts

This has the same dimensions as https://www.thingiverse.com/thing:2494413.
This is a small bunker that should work for human size characters in the 25mm to 28mm scale. I did this in inches rather than metric and the floor tiles are 1 x 1 inch and the walls are 1 x 2.25 inch panels. The door opening is 1 inch wide and 1.75 inches high. with the roof, the total height is 2.375 inches. The roof also has a 1 inch grid.
