1x2 Furring Strip Connectors

4 Corner connectors:

• Print all four twice to make a cube (up-left up-right down-left down-right)

• Cut 1x2s to desired lengths

• Screw together with small cabinet wood screws (hole guides)

• Reinforce layers with a single bolt, nut and two washers.

• Use a custom support (Normal/grid works best) but avoid supporting the through-holes.

I have a couple of other variations:

• a "T" section

• a "T+1" corner

• a "plus" connector

• a "3d plus" connector

• a "3d plus -1" connector

• a "union" to reuse scrap
