Yes the feet are also made from 15mm clear acrylic. Lettering are done at the same place. Actually it is laser engraving on acrylic and filled with some acrylic/fabric paint.
There is another place here dealing with sheet metal works. Last weekend i had visited their place to see some sample works. They have all the machinery for bending, powder coating, anodizing, vent cutting etc. I will visit them after two weeks to order few cabinets for amplifiers and active X-over. They also do the lettering on metal using Lith printing.
