A simple OXO cube holder to mount inside a cupboard door. You can grab the cube at the sides if you have small fingers and/or nails, or just flick one out using a fingertip underneath. There is a retention lip, so they shouldn't come out as the door shuts.

Everything is configurable if you need different sizes. I haven't enabled the customiser as it annoys me, so let me know if you need a different config.

Eight cubes is just under 180mm high, which is the max my printer can do. Note the extensions to get you up to 12 cubes, so a full box.

Thanks to Chris Harrison for the idea, but we needed shorter and wider.

(Note I neatened up the design after printing the one in the picture to remove the seams down the front.)
