Balls, Cross ribbing

Christmas ornaments in the shape of balls. Available in three sizes: 40, 60 and 80 mm. Different number of double ribs (depending on the size of the ball): 6, 10 and 14. Rib width 3 mm. Print the bottom part with a support so that the curve is printed well and the ball sticks better to the backing. The top of the ball is adjusted so that it does not need to be supported.
