Ikea Lack Corner Leg Brace

This leg brace mounts on the underside of the table top, against the inside of the legs, flange up. 

Print 4x with the flange side down. 

Takes 7x #8 Screws to fasten. You may not need all of them, but this brace will make your Lack super stiff and keeps the legs straight. Use short screws (½-5/8) or you'll hit the stud.

It's a little overkill, but they stay out of the way. Probably not compatible with any type of enclosure system as is. Enjoy!
