Small top hat tube greeble
Small top hat tube used in a lot of places in OT props and sets, Falcon guns console, Xwing controls, interogation droid....
12mm diameter, 13mm high
from what I can count, 3 used on the falcon console, 2 on the Xwing controls, 8 or 9 on the interogation droid that I can see (one is missing on the Dedalino pen holder in some pics).
this is a tube throughout, it will need to be glued to your props.
