inside-cap screw container, various sizes (incl. pencil case)

A small cylindrical container with a lid that screws inside the top. 

A generic small container for a travel essentials contest seemed a bit of a stretch, but I actually did take one or two similar containers on my last few vacations for various small items (like USB sticks and adapters etc.) which otherwise could get lost in the depths of my bag/suitcase.

If you use the lid the other way around, there's a slot for a coin, big screwdriver or similar to screw it in/out it.

Diameter D and height H are inside dimensions. The D26 H56 also holds 25 2€ coins. Some moderate re-scaling can be used for different sizes. (You can scale z independently of x&y). Further sizes can be requested.

EDIT: Added two bigger sizes (D30 H150 and D40 H150) that can be used as pencil cases.

Printing:

I used PLA (Prusament Marble Grey, Galaxy Black and Galaxy Green) with a 0.4mm nozzle and 0.2mm layer height for the body and 0.17mm for the lid.

Load the STL, split into objects, right-click the lid, add “layers and perimeters”. I also like to activate output options → complete individual objects to reduce stringing.
