I naturally suggest mine, available at

I've ordered handles in "strong and flexible, polished", from
Shapeways.com. They aren't cheap, but they're easy and they
do work well.
I've had good luck just spray painting them with an appropriate
paint. Shapeways' color choices for dyed parts are OK, but not
particularly close to the original colors. If you decide to go with
the dyes, you'll want to use urethane floor polish or the like to
seal the pores and provide a satin finish. If you don't seal the
pores, they pick up dirt, and are a bear to keep clean.
Finding the switch bodies to put them on is challenging.

If you want the actual 8/E PCB design, I've re-drawn the bulb PCB at
Here's the big list of other PCBs I've drawn, for what that's worth:
If you're wanting a panel for a modern micro, I concur with the
recommendation or Oscar's 8/I replica as a starting point. Interfacing
the pi to something behind Rod's front panel artwork would be pretty
cool. (Though I'm a bigger fan of the 8/I panel, myself.)
