This is a simple trashbag holder optimised for vase mode.

The big one has an inner diameter of 80mm and a inner height of 180mm.

The small one is 50mm by 130mm.

You can tape it or drill small holes for screws.

Both had a wall of 2mm and the bottom is 1,2mm.

I printed both with a 0,6mm nozzle @1mm wide and 0,4mm height (3 bottom layers)

The big one only took 1h17min with my volcano hotend.
