So for the Build something contest over on the LAF forum I made the firebase you can see above. These are two terrain pieces roughly 40x80cm big. The fit against each other to form a 80x80cm terrain piece.
The Sandbags and other parafrenalia are 3d printed on a resin printer. The rest is scratchbuild. The roofs of the bunkers can be lifted up to place miniatures inside.
Here are some pictures of the bunkers during the build :
Next I build a base were the individual bunkers fit in:
The white sandbags were made out of DAS clay. Now the ground got a basecoat of paint and I added some smaller items like smoke grenades, C ration bags, warm food containers etc.:
Then all the bunkers emplacements etc got a black basecoat.
And this is the finished firebase:
I build the two terrain tiles to be able to insert a middle par as needed. So I will build different middle parts in the future like gun pits or a landing pad for choppers etc.
