Stackable Beanies Coffee Jar Tray

My wife likes [Beanies Coffee](https://beaniesflavourco.co.uk/), but the jars don't stack so well. This is a remix of my original [Beanies Coffee Jar Stacker](https://www.thingiverse.com/thing:4726579), extended to generate stackable *x*×*y* trays. My wife is happily stacking four levels of jars on 2×2 trays. Make sure you use a tray under the bottom layer of jars too to ensure that no jars move. If you want to stack any higher then 1) you may wish to reconsider your relationship with caffeine, and 2) you probably want to move to the 3×2 tray (or print even larger ones) to increase stability.

I've produced STLs for the following sizes:
* 1×1 jar stacker. This simply clips over the lid of one jar so you can safely stack a second jar on top, much like the original. The one difference is that there are now holes in the sides to allow air to enter when you lift the top jar.
* 2×2 stackable tray.
* 3×2 stackable tray.

I've also included the [OpenSCAD](https://openscad.org/) file
