Vertex K8400 Extension feet

I made this for the purpose to install a larger 400W PSU to be able to retrofit a heated bed to my Vertex K8400. These feet will elevate the whole printer by 19 mm which should be enough to make some space for the bigger PSU to "breathe" as the fan is facing downwards.

Just push the existing feet down into the cylindrical shape using some light force. The extension should remain snugly fit onto the old feet.
