My YAMAHA RX-V479 AV Receiver did not fit into my sideboard. To reduce size, I created a replacement for the 4 feet. This gives the receiver much more headroom for cooling while still providing enough space on the bottom for air ventilation and protect the plastic parts that are standing down.
I printed this with my Prusa Mini with 20% infill and no supports (You can print it with the hollow side facing downward)
