IKEA Lack L bracket

I keep P1S on IKEA Lack table and on high speeds it wobble, so i made this bracket to keep it more stable.With brackets installed it is more stable, still wobbles a bit but less than without them. So I thing it's a good quick fix. I've used 3.5 x 25 mm screws for securing brackets onto the table. No support needed, print with plastic of choice.
