These tank traps aim to represent the specifications from here, adapted for tabletop wargaming: https://en.wikipedia.org/wiki/Czech_hedgehog
You need to print Leg_Basic once and Leg_Connectors twice. Make sure to NOT use super glue when assembling, as this will not allow you to pose them correctly, it will stick them together in the random pose you just had instantly and you will not be able to correct it any more.
These models are optimized for resin printing, if you have an FDM printer, they might be a bit to fragile. If you want an FDM version of them, I could also do that.
