Ikea Norden Folding Table Riser Feet Parametric

Just basic rounded over cubes to raise the table to a better position. You can adjust how much additional height you want and how many screw holes to use (1-3 for the outside and 1-5 for the inside). 

I glued the feet on but still used the screw holes for the added strength from the additional walls. The provided stls raise the tabletop from 74cm to 79cm.
