[DIYbio] non-cassette, but modular Gelbox

All the cassettes I have seen are complex, partly sealed with many pieces made by injection molding.

An open topped tray or set of channels that all have contacts and get
volts as a group when you load them would be enough, and it could be a simpler shape
than any cassette parts. I'm not sure 3D printing is ready for the low prices you'd want,
but a combination of laser cutting of plastic like polycarbonate or the UV clear acrylic,
plus some CNC milling out of wells and channels is. Contacts might be a batch run of metal
rectangles folded into a C shape that clips around the ends of channels. One leg of the
C would contact cast gel, one leg would contact another metal contact that is
part of the electrophoresis volt source module that hold the channels during a run.
