This is a 30x25x18cm (ish) 3 layer shelving unit.
I designed it to help organised the Tupperware in our kitchen cupboard but these would be great for anywhere.

The parts will just fit on an Mk3 print bed, but you may need to check your skirt distance (or turn it off entirely).

The shelves themselves use 6mm thick, 30cm long wooden dowels.
I used these ones but you can obviously use any length dowels as long as they are 6mm diameter, so you could use these ends and make different length shelves.

One end has a cut out next to each hole. That's because, once you've placed all of the dowels into one end, it's very fiddly to fit the other end on, so if you line them up against the cutout and slide them in, it becomes far easier.
I've also included a 3rd part called the “aligner” which is an optional tool that you can use to help align the loose ends for inserting into the printed part.

I've popped a little bit of glue to both ends of some of the dowels which is more than strong enough to make sure it holds together. There's already sufficient tension on them but it just helps keep it together if someone picked it up by an end and carried it around etc.
