UPDATE 8/12/17 : Robot on Base Version 2

Tamiya Gearbox holes align correctly
Switch snaps easily into the base
Paper removes much more easily than earlier version

DETAILS:

We were eventually able to settle on one machine screw fastener size: 3 mm Diameter 10 mm long.
 
  However the ONLY fastener that we can find that will fit the Arduino holes in the Uno V3 layout is a standoff with a small hexagonal cross section. 3 major USA suppliers do not have machine screws or nuts that are that small in cross-section. Rumor has it that there is some Japanese standard that may be smaller. Maybe next year.

Fastener Bill Of Materials:

12 - 3mm diameter 10mm long pan head machine screws (steel)
8 - 3mm Standoffs with 8mm tall hexagonal body and 6mm long threaded post (brass)
6 - 3mm hex nuts (steel)
