SIDAM 25 SPAAG
It is an m113 with a turret made by OTO Breda and houses 4 Oerlikon KBA cannon.
model in full dimensions in blender 2.79b and scaled to 1/100 for the .stl file
scale down to 35% in the slicer.
as usual, the dice are 15mm for reference
if I can't print it, I don't post it.
The barrels are too tiny to print in 6mm, so you'll need to glue a short piece of paint brush bristle in the proper locations for the barrels.....
If only resin wasn't stinky and expensive, I'd get a SLA printer.....
