Inspired by the "Barrel and Ball Puzzle" first described in
Professor Hoffmann's "Puzzles Old and New" published by F. Warne (1893).
Pop a marble in the barrel, close it up and pass to a victim to remove.
Print AllParts.stl and add a marble.
This thing uses Karl Maximilian's screw thread library (Thingiverse 31363) place the screwthread script in the same directory.
If the screw thread is too tight/loose adjust the tolerance in the OpenScad script and just generate/print the BarrelEnd part. The thread should be tight enough to prevent the base of the barrel being turned just using finger pressure.
The marble should have a diameter of 15 or 16mm.
The barrel does use quite a bit of material in the upper half to enable the top to be printed - any suggestions on how I could minimise this greatfuly received as I'm new to OpenScad/3D design!
