This stash box is about a 2" (5 cm) cube. The cap fits flush. It's a pretty tight fit. You need the Weed-key to turn it. It's the same principle as a locking lug nut for car wheels.

Note that the thread is left-handed. To open or close, turn it opposite the "normal" way. Even if mom finds the key, she probably won't get in. I laughed the couple of times I've turned it the wrong way...

Parts easily fit on the little 5 inch Afinia build plate. Default settings, but reduce the support angle to just 10 degrees, so there's no support in the threads. 2 hours 30 min, 75 grams ABS, 0.3mm Z.

Work the lid back and forth, on and off, to smooth things out.
I forget which project's weed leaf I used for this. Thanks to somebody...
If your software allows all 3 parts to be temporarily "joined", and then together, scaled somewhat larger or smaller, it should work out fine.
