Kicker Ball / Boccia Pallino Ball / Pendant

Ball for foosball or for bocce the pallino ball (for scaling please read further) or also as a keychain
For toys or building blocks, the keychain version of the simple sphere can serve as a wrecking ball 😉

Many pre-made color variants are available

The models are designed so that no support filament needs to be removed → Print, glue together, done

Avoid rotating the components, the alignment on an axis improves fitting accuracy If the cube is rotated so that the sides are not on the X/Y axes, ripples can occur on the side surfaces, which leads to the cube lying inaccurately in the hemispheres and a gap forming

Gluing together:
Before gluing, check how well the hemispheres fit together If necessary, sand the cube if a gap is visible (hold the ball against the light and see if light shines through a gap)
As adhesive, I use Pattex Special for model building (see picture) This adhesive is very fluid and optimal for precise bonding If you only have thick adhesive, you should reduce the cube by 0.2mm before printing (under Processes “Objects” select the corresponding cube)
The top and bottom of the connecting cube (the ones with crosses) must be inserted into the ball halves so that both crosses are still half visible from the side (see pictures)

First, apply adhesive to the opening of one ball half and press the cube into the ball half as firmly as possible as described
Then apply more adhesive to this half and place the second half on top, align, and press firmly together
  

The following ball types are available as templates:

Simple ball/sphere, soccer ball, basketball, volleyball, tennis ball, golf ball, and water polo ball

Ball for foosball to glue together

32mm diameter → approximately 20g heavy

When scaled to 35mm → approximately 26g heavy

Scaling:

30mm =   93.75%

31mm =   96.88%

32mm = 100.00%

33mm = 103.13%

34mm = 106.25%

35mm = 109.38%

36mm = 112.50%

37mm = 115.63%

Keep in mind: The surfaces are susceptible to impact Therefore, the balls are not suitable for competition but are intended only as a replacement or for hobby use

Pallino ball for bocce to glue together

Dimensions for competition:

Minimum allowed size: 39mm

Maximum allowed size: 41mm

A pallino ball for competition weighs up to 90 grams and is made of metal, this weight cannot be achieved with PLA

Scaling of size according to competition specifications (but not competition weight!) :

40mm =  117.65 (41.7g)

Note:

A plastic bocce set from a toy store has a pallino ball with approx 33mm size and 17g weight

Scaling in toy quality:
33mm = 103.13% (17.04g)

----------------------------------------------------------------------------

The example balls are printed with PLA, with a layer height of 0.08mm (to better represent the contours) and with a 0.4mm nozzle, 100% infill, and surface smoothing

The balls are not suitable for competition but are intended only as a replacement or for hobby use
