Just a simple hanging basket with screw holes to mount it anywhere. I hang them up next to my printer to organize all my printer stuff (glue sticks, Bed cleaner etc...)

It's 150mm wide x 150mm tall x 70mm deep

It has notches for stability to keep it from twisting. The walls are fairly thick too so I wouldn't go too crazy on the infill. 10-15% is more than stable. maybe even less if you do more than 3 walls.

I print it standing up with no supports. I know this isn't the strongest orientation but it has caused any issues so far.
