Parametric Customisable Can and Jar Stacker

This is an expansion on my Soda Can Stacker, and gives a lot more flexibility in design.

This customiser allows flexibility to create short or tall sleeves for stacking jars, cans, soda cans etc. as well as creating stackers in a matrix for six packs, 8 packs etc. It also allows inclusion of a flat shelf ring between the upper and lower parts if required to keep the stacker in the right place (such as the included Jar Stacker and Tin Can Stacker). Create a short sleeve to sit on a can, jar, soda can etc. which allows another similar can or jar to be stably stacked on top. Great for stacking individual cans 2 or 3 high in a fridge or pantry.

Create a taller matrix caddy (e.g. Soda Can Six Pack) to fill with cans - sit another filled caddy on top for a very stable block stack (e.g. stack of 12 if using two six pack caddies). Great for stacking in your car fridge/caravan fridge/cooler bin/caravan cupboard etc. where there's movement and you want to keep your jars and cans steady and stable.

Make the stackers as tall or short as you like. Make the walls as thick or thin as you like. Include a ringed shelf inside the stacker between the top and bottom portions, but you will need to use supports when printing those. If you're concerned about particular dimensions, check the Echo statements in the OpenSCAD console window for dimensions after the preview has rendered. I've included a cross-section preview so you can check internal shapes during design - handy for the weird bottom of some jars. Dimensions in the models are internal, which means you just plug in the external dimensions of your jar or can. I've included the .json file for the .stl models so you have some examples.

I hope you find this design useful. Happy printing.
