LACK-ing a shelf?

This can be used to mount a shelf board to the hollow legs of an IKEA LACK table.

Assembly instructions:

1. Print four of the parts.
2. Use one of the parts as a template to drill the holes into the hollow table legs using a 4 mm drill.
3. Insert two M4 square nuts (7 mm x 7 mm x 2 mm) into each of the parts and attach M4 screws (16 mm in length or so) into the nuts.
4. Hold the parts against the legs and turn the screws further so they mate with the holes in the table legs.
