My New IKEA Table had a stabilization bar running just under the table surface, blocking me from using a piece of furniture I had from another setup, so I made this riser foot that raises and then also holds around the foot of the table.

I used the 5cm riser foot, and I made a bunch of sizes available, I could of course make it higher than 6cm, but I feel that this is becoming too precarious and therefore stopped.

I wouldn't go above 6cm, not stable enough, you have been warned :-)
