A container for poker chips.
The set I own came in a very long case, which is annoying to store, and
has more chips than I ever use. It's also overly heavy to take to a friend's house.

Print a "tube" and a "cap" to hold a small number of chips.
The cap screws into the tube (so the chips cannot spill out).
Alas, this cap can easily be ripped out, rather than unscrewed when the tube is long.
Less of a problem when using a stiff filament.

Combine 6 of these with "caddy", "lock" and "handle".
The alternative "smallLock" only locks the tubes in place, but allows the caps and chips to be removed.
I prefer the larger lock, because I hand each player an entire tube of chips,
so I never take individual chips from the caddy.

"cap" has an alternative with "dealer" written on it to act as a dealer button.

Caddies can be loosely stacked (there is a hole in the base which accomodates the handle)
Caddies can also be screwed together, with only the top-most caddy needing a "lock" and "handle".

The default "chipsPerColumn" is 30, therefore the default caddy holds 180 chips.
