Hello,
Here's a quick remix of @mkoistinen MK4 side bin, but using two M5 screws to firmly attach it to the printer, as I didn't want it to be wobbly. I've also changed the inner radius (5mm), as I found it too big on the original model
You will need 2 M5x10 screws. For the nuts, you can use this excellent model from @maurimulon https://www.printables.com/model/269120-t-nut-m5-for-prusa-mini
Print at your preferred layer height. No support needed.
