Ikea Corner Cabinet Lazy Susan Riser

This is an adapter design to allow raising an Ikea lazy susan shelf by 15mm. I designed this because the bottom shelf of our apartment's corner lazy susan shelf would just bump the door hinge when you swung it out.

This is designed to snap around a 25mm diameter center post and then sit on top of the cross support bar that sticks out about 4.5mm on each side. Then the existing shelf adapter sits down on the top supports.
