Hockey Puck Stash Box (Screw-Top)

A hockey puck that unscrews. Outside, it's a 1:1 copy of a regulation puck (76.2 x 25.4 mm) with the diamond texture on the side; inside, there's room for a nicotine pouch can, pills, guitar picks, coins, a spare key, whatever fits.

Inside dimensions: 69 mm diameter, 22.5 mm deep. A standard Velo/Zyn style can drops right in. Measure yours first; cans vary a bit between brands.

TWO LID VERSIONS

- lid_regulation - keeps the whole thing at true puck height (25.4 mm).  Looks right if you want it to pass as a real puck.

- lid (beefy) - 6 mm taller. Much nicer to use; you get something to grip, so it opens and closes easily. Total height 31.4 mm.

Print one of each and see which you like. I use the beefy one.

PRINTING

No supports, no brim needed on a clean sheet. Both parts are already oriented; don't let the slicer auto-rotate them.

- 0.2 mm layers are fine; 0.15 mm if you want the side texture crisper

- 3-4 perimeters

- Bottom fill: Concentric, gives the cleanest flat puck face

- Black filament obviously

Thread is a trapezoidal 2.5 mm pitch with 0.2 mm clearance, tuned for a 0.4 mm nozzle. Prints and screws smoothly on my stock PRUSA CORE ONE. If your lid comes out tight, a bit of XY compensation or 0.05 mm more clearance sorts it.

SOURCE FILES

The .scad file is fully parametric: diameter, height, wall thickness, thread pitch and clearance, and lid height. The Python script regenerates the STLs, including the side texture (needs OpenSCAD plus manifold3d/trimesh). Resize it for a different can, or a different object entirely.

Remix away. If you print one, post a make; I'd like to see it.
