I created this to raise my desk 11mm so a cabinet could fit beneath it. The desk I purchased is this one with round feet:

If your feet will fit into a 71mm round hole, this should work for you too.
Fits the feet well with a little wiggle room. Printed at 40% infill for support, but could probably do less and save some filament if you want to take a chance.
