I designed these inserts to allow me to put my Ikea Alex desk on casters for easy movement.
It's designed to work with these casters. https://www.amazon.com/dp/B010SLSK48/ref=cm_sw_em_r_mt_dp_T3N819BY7C22FKNM1VSV?_encoding=UTF8&psc=1
I printed it with the following settings

4 perimeters
50% gyroid infill.
