Well, it's a ball ;)
You can print it without infill and without support. It has a flat bottom that makes printing easier and the ball able to stand without rolling away.

See my reel in instagram how I printed several of them in a row. A modified the created gcode file by duplicating most of the content used to print a single ball and add following lines in between:

;REMOVE PRINTED PART START
G1 E-1 F300;retract the filament a bit to release some of the pressure
M104 S100;let the extruder cool down a bit
M140 S0;turn off bed heating
G0 X100 Y200;move to waiting position (half x-axis, full y-axis)
G4 P480000;wait 8 Minutes to cool down
G0 Z5;move head down
G0 Y0;push printed part off the bed
;REMOVE PRINTED PART END

(My printer uses a marlin firmware)
The basic idea is to move the printing head behind the printed piece, let the bed cool down, shove the printed piece off the bed and start the next print.

That way I was able to print a full filament role in a row. It tool 5 days but it ran in one big print, producing 25 balls :)
