I needed some barricades and blockhouses for my Primosole Bridge board and I couldn't really find what I wanted so I created my own from scratch in Tinkercad and printed them out. I'm happy with the result, I printed one of each then printed the barricades as a mirror image so I could have plenty but if I need more... just press print. Concrete blockhouses and barricades printed on a FDM complete with 'Mold lines & striations as part of the manufacturing process" without any extra effort! (Well that what I'm telling myself.)
The blockhouses will fit a 60mm base.
P.S. Dan, great idea I will also print some 'risers'; so that the MMG and antitank gun teams mounted on a 60mm base will be able to be see (and be seen) through the firing slit, has to look good for those photos!
