Ikea Lack Table - Aldis Leg Adapter

UPDATE 9/6/16:
Minor tweaks. Increased the thickness of the walls on top, aligned the inside edges properly. Should print fine now with a wall thickness of 1mm

UPDATE 9/5/16:
I've done some test prints and fittings. I've altered the top of the adapter so the top legs will sit directly on the bottom LACK. I've also adjusted the measures slightly so it fits the Aldis legs better.

I'm planning to use the Ikea Lack table to create an enclosure for my Monoprice Maker Select v2,
