Dimensions of the boxes are 130x180x180mm, so it's printable on small printers like Bambu Lab A1 mini and Prusa MINI.

They have a capacity of 50+ big pods or 120+ anti-calc cartridges.

I also uploaded versions with 4.5mm holes to connect the boxes with srews (M4x10 & nut). Another way is to use duct tape on the back and bottom side.

No supports needed.

Don't print too fast!
