A simple round foot for IKEA OLOV legs (diameter approx. 38.5mm). I made these to reduce my desk's tendency to slip on my office's bamboo laminate floor.

The foot adds at most 7.5mm (about ¼") to the height of the table, depending on the stiffness of the filament and the amount of infill. The inner diameter of the foot is 40 mm, and this model will scale well to fit other round table legs.

I recommend printing with TPU or another flexible filament at standard settings, with a 3D infill like gyroid or cubic.
