This is the first round of 3d printed terrain for tabletop gaming that I made. It's clearly based on the classic concrete 'jersey barriers' seen along highways.
I've included a complete one and 3 variants of blasted ones. The sketchup file is provided if you want to modify the blasted shapes.
The full model is 33mm tall. It looked too big so the other 2 are printed at 75% scale. At 75% scale its ~25mm. Note that this is important to many games as less than 1 in makes it passable terrain. All files are 33mm in the stl.
Scale to fit whatever game you're playing.
The pointed top one was for trying to print it hollow. I think it just looked too ridiculous so I went back to the classic shape.
