Parametric 18650 stackable vase mode tray

Keep your recycled 18650 batteries neatly stored with this stackable tray.

I was getting paranoid about kids running around and shaking things, so I designed this tray to keep batteries safely oriented. While I was at it, I made it stackable and printable in vase mode. They are very light - 20g of filament for a 6x tray.

I printed mine with a 0.8mm nozzle, 0.4mm layer height and 1.2mm extrusion width.

In OpenScad model - just tell how many batteries you want per tray.

Please post your makes if you print this.
