This is an expandable hexagon wall mounting shelving system that was inspired by the very honeycomb looking "yellow" PLA from hobbyking.

First print the testfit file to make sure the connectors will slide together. They should slide with some friction. If they are too loose adjust the tolerance setting in OpenSCAD. If they are only slightly too tight a small amount of sanding should be all you need.

Hex_shelf_80 - 80mm deep shelf (recommended)
Hex_shelf_160 - 160mm deep shelf (like in the photo)
Hex_shelf_hanger - These screw into the wall and are a tight friction fit to hold everything in place.
Hex_shelf_insert - optional insert shelf for small items.
