I needed some space to store my spraybottle, IIRC it is a 500ml one from Ikea, that I wanted to have close to my printer on a Skadis.
Simple design and should fit any bottle, or round object for that matter, with an outer diameter of 70mm.
It uses one of the universal hooks (Skadis_Universal_Hook.stl) from CSD_Salzburg over at Thingiverse.
The author marked this model as their own original creation.
