-16mm x 32mm plates (with tetrix hole pattern)
-28mm (and/or 32mm) "L" brackets (32mm C-channel minus one side)
(we use these last two [we make them from the larger parts] to build primary structure by connecting C-channels to each other--28mm will go inside the openings of the C-channels)
-28mm stand-offs (we would use these to reinforce C-channels by "closing the box") (32mm would be nice too)

I'd add:

Worm gears
Universal joints
Racks
Ruggedized DC motors
Hinge w/Tetrix bolt pattern

Also, a part that my team found very useful is the omni wheel connector hub. We use them to reinforce/space bushings where they pass through the Tetrix channel and it would be nice to be able to buy them as a stand alone piece.

I'm going to go out on a limb here and say along with all of the above. I think the addition of something I think could be nice. What about the addition of some "heavy pneumatics" Not lego with the restricted stroke, but something like an SMC piston with very small bores and a small air accumulation system. It was just one of my crazy thoughts

Also, what about a gear that fits inside the channel?

P.S. Homemade FTC bevel gears are not fun to make...
