About this 3D model

Cavern wall system with pin lock. 52 different cavern walls can be connected each other with pins ( I tested pin locking system turning pin 90 degree clockwise locking pin inside the connection parts. Also, Pin slots have 2 mm upvard incline allow parts to be tightly connected. Each pin takes 15 min to print) I think making tight connections allows caverns more sturdy maps and allow players not to destroy already made maps. Pins can be turned with a screwdriver or key part i will design to turn parts Each part can be print 220x220mm Main scale 28 mm can be scaled down to 25 mm
