Ball Bucket Extender for Pongbot Nova S Pro

I wanted to fit more balls in the ball bucket for my table tennis robot Pongbot Nova S Pro.

It's made in two or four parts depending on the printer size.

The effective height of the extender is 80mm.
It is infinitely expandable.

The 2-part model is 190x176 mm big.

The 4-part model is 176x95 mm big.

It works without any screws or glue. 
But it can be screwed together with M3x6 screws for added rigidity.
For a nice flush look use ultra low screws, but any head type works.
As an option It can be glued together. 

To avoid lifting on the printbed it's recommended to add a brim of 3mm.

Gluestick can also be used for added security to the plate.

No support should be needed. Print orientation is to print it with the U-channel up, see picture.

Mine printed fine with 0.6mm nozzle and 0.35mm layer height SPEED setting.

(In my picture of the print in action there is a gap between the two halves, but that is now fixed, but i didn't print a new one because it works as it is.)
