The 312B is 1/12th - or do you mean the pod? I have no idea, lol.
As far as cutting, I cut one to where I thought it look good, and then cut the other 4 to match that one - by hand, no templates! No foolies!

Yeah, the Probe Droid is the newer fuzzier model:
HAN: It could be a speeder, one of ours.
SENIOR CONTROLLER: No. Wait -- there's something very weak coming

CONTROL PANEL SPEAKER: "mewwww mewwww mewwww"
THREEPIO: Sir, I am fluent in six million forms of communication. This
signal is not used by the Alliance. It could be an Imperial code.
The transmission ends in static.
