Aluminium/cling foil or baking paper holder

My goal was to create a simple model that requires no supports and would print in an acceptable amount of time. For this last requirement, I made the walls 1,8 mm thick (as I am using a 0,6 mm nozzle - you can safely set 0,6 mm line thickness with a 0,4 nozzle too) - a happy middle ground between the number of perimeters and sturdiness.

The inner dimensions are 50 × 50 × 225 mm, so all common foil boxes should fit. My printer's max print height was a limiting factor for the height of the model :)

There are single and double versions.

For mounting, I used double-sided tape placed on top, in the middle, and on the bottom (tape up to 20 mm wide fits perfectly).
