These are two designs to pile up mugs in places where there is not much horizontal space. There are two versions, the O and the X. The X is much faster to print, but not as stable as O. Print them both and decide which one you like most.

These are designed for the 8cm diameter mugs.

Resize the model to your mug size. Walls are 1mm in each side, so if your mug has 10cm of diameter, resize the model to 10.2cm (I would suggest to 10.3cm, since that 1mm in each side is also resized).
