I've been packing for a week-long hike and needed a container for lip balm and salt; I wanted ones that weight less than those small travel containers available in drug stores and that are sturdier than zip bags. So I reworked [my previous design](/thing:4650384) to a fully customizable version.
The containers did well; although the screw cap is not airtight, the lip balm did not leak despite melting due to the heat.
You may just print the sample `.stl` files, but I recommend you to load the `.scad` file in OpenSCAD and use the customizer interface to tune the model to your needs. The parameter sets that I used are in the `.json` file, in the format understood by OpenSCAD.
The main differences compared to similar models is that this container is highly customizable and uses less plastic (=less weight) for similar volumes.

The design lets one customize the size of the item: the inner diameter at mouth of the container (`iDia`) and the inner height of the container (`iH`). If the diameter is large and the height is low, one gets a jar, if the height is on par or larger than the diameter, then one gets a bottle.
The bottom of the container can have a bigger diameter than the mouth by configuring `bottomExtra` parameter, and the cross-section of the bottom can be either round, or be waved to have a configurable number of sides (by adding a sine wave of specified amplitude radially). `waveCnt` and `waveXY` configure…
