MODIFIED - Screw holes moved as apparently they were not aligned properly, apologies to previous downloaders.
If you decide to remove the base cover from your RL200 to improve airflow and reduce the risk of overheating, you lose the built in feet.
So I designed some replacement corner pieces that would take some M8 screw in adjustable feet that I had spare.

NB. Now modified as the previous version did not allow for the small step-down from the bottom edge of the case to the support piece with the screw holes.
Still not yet tested for fit as I bodged the originals and used them, but should be OK.
