I created a mini stool that is really easy to build, you just need to click the parts together.
The stool consists of three parts, two pairs of legs and a seat.

You can of course use it in other ways, for example as a stool under a flower pot.

The total weight of the stool is 460g with a 10% gyroid filling with three perimeters and a print time of 10 hours.

I used the basic two perimeters and a 5% gyroid filling for a faster print, but the load capacity is also decent, I could sit on it with my 80 kilograms without any problems.
