The file 'Cavern Riser Blocks – Stackable 3D Printer Model' is (stl) file type, size is 2.3MB.
This is just a small alteration on the awesome cavern riser blocks to make them more sturdy when stacked. They should fit all Magnetic or pin versions of the OpenForge bases and allow secure stacking without additional connections.
If you stick the Riser on a base itself, they seamlessly fit with other tiles and allow for infinite stackability :D
