Macintosh Portable Bag Foot

The Macintosh Portable came with a nice bag. That bag has firm rubber feet that stick out from the bottom, thus eventually getting knocked off. This thing is a replacement for those missing feet.

I printed in PLA, because that what my school's printers will do, but if you could print it in a firm slightly rubbery material, or perhaps coat an ABS foot with a nice tacky/rubbery coating that would be better for durability.

The dimensions are as close as I could get them to exact. the internal braces are slightly different but the receiver holes for screws from inside the bag are in the same place as the originals.
