Measurements listed  if they  were mentioned..otherwise you're on your on your own...
  3inch PVC scales out to about 75mm diameter, good for the SADAR...
The RPG scales out at 60mm, to be about 2 3/8 tube, not really big enough  to house many  posters.
I'd make  a HIMAT launcher assembly, it has a handle.., Make a decent tote if you  built it right. 
Go now...create!
