What COTS parts would you like to see?

Mostly spacers, standoffs, and more shaft selection.

Spacers

• 1/4 Threaded spacer for 1/8" and 1/16" 1x1 and 2x1 Al tube
  
• Delrin spacers for 3/8" hex and 1/2" and 3/8" round
  

Standoffs

• Common standoffs availble through Vex/AM/WCP to save on McMaster orders
• Round and hex variants

Shafts

• Thunderhex-style 3/8" hex with bore and similar variants for 1/2" and 3/8" round
• Some grinding on the thunderhex to improve fit with hex bearings
• Perhaps some steel variants of the current thunderhex/bored round shaft

Also, a more robust option for VP encoders. As mentioned above, plastic would be nice, but the boards and wires themselves need some sort of reinforcement.
