This is my take on the popular Ikea Lack table riser. I needed something that printed quickly for my Anet E10. This is a very basic model, but doesn't incorporate any features for the mounting of side panels, so I have included the file so that you can edit it and remix it. This was my 1st every design using Fusion 360 and it came out perfect the 1st time around. 

Print with supports ‘touching build plate’ only.
