I design this model to fit with the Anycubic Kobra 3 so that it can catch filaments while it's slinging the filament poop.

The sling attachment could be printed without support but printing with support would have a better finished. (Only support overhang that is 45 degree up)

Bin can be printed with no support.

The wall are thin so I printed with 100% infill, or you can do 3 wall loops to add strengths to it.

6/30/24: There are now a larger bin size.

I also added a photo where I use support for the model.

I explain the whole process here:
