I created this rack in two variants. One is accurate with no gap between the balls and the rack (9ballsRack). The second one has a gap of approx. 2 mm and the balls are looser in it (NineBallsRack).
Printed with PLA with 0.4 nozzle, 0.2 layer, infill 30%, no supports.
The author marked this model as their own original creation.
