Icosahedron Joint for Square Tubing

cults3d

This is a joint to make an icosahedron with square tubing, or wooden sticks, or anything with a square cross section. As supplied, the model provides a 25 mm square hole, 37.5 mm deep. To make the complete icosahedron, you'll need 12 of these, along with 30 sticks or square tubing of equal length. This should be easy to print as long as your printer can handle a 58 degree overhang.
