LACK Attack #1.5: Stack More Lacks

This is expansion of the LACK Attack #1: Stack the Lack. The original model allows the LACK tables to stack only to height. My addition allows them to be stacked also side by side.

• LackJoint_a is intended to be put on top of the LACK legs when you need to stack two side by side, or to bottom of the legs to the lowest tier of LACKs.
• LackJoint_b is to be used on bottoms of two LACKs when they are on top of others. The “lips” prevent them from sliding, as on the original LACK Attack #1.
• LackJoint_c is when you need to stack four LACKs.
