Cylinder twist box for spiral vase mode

Last crawled date: 5 years, 5 months ago
There are other spiral-vase-mode twist-closure boxes out there, but they were all too pointy; I wanted a compact cylinder with shallow threads and just the right amount of friction. As I printed them (0.45mm extrusion width), the "inside" cylinder is about 2 mm smaller than the base diameter.
The original usage of the 52 x 80 mm cylinder was to contain & protect a stack of crackers for hiking and camping, but they will work for other objects or stacks or bundles of objects: coins, camera lenses, telescope eyepieces, matches, cotton swabs, etc.
PLA works for this too, but for food storage I prefer PETG and a food-safe nozzle.
The 80mm diameter example is nearing the largest practical diameter (perhaps not rigid enough) for 0.4mm extruder, but maybe larger extruders can make larger cylinders work.
I added 22mm x 50mm and 80 x 50mm examples. If there's some interest, I can upload other sizes; if there's a lot of interest, I'll set it up in Customizer. Or you can edit the OpenSCAD file yourself, the comments should explain it; let me know if not.
