Shelf for IKEA table

I created this DIY stand to print and add a shelf to the basic IKEA table, so I can store boxes or other items.

One M3 screw and nut are needed for each table leg.
A square profile bar is required. Dimensions: 500 x 10 x 10 mm (length x width x height).

it was impresed on a Kingroon KP5L (300x300mm)
