CORNICHON | Pickleball rackets set, fast print

Beach days are coming! 
Fast-print your set of pickleball rackets to show off some skills with style at the beach or at the park!

They come in 3 sizes, to accomodate most printers. The paddle sizes are:

• LARGE: 210 x 182 mm
• MEDIUM: 200 x 172 mm
• SMALL: 150 x 150 mm. They print fast:
• 45min for the Large paddle
• 1.5 to 2h for the handles.

With the insert for the handle, the paddle models are a bit longer than stated above, but where designed so that:

• the LARGE can fit on a 256 x 256 printing bed (Bambu Lab A1, X1, P1 and equivalent)
• the MEDIUM can fit on a 250 x 210 printing bed (Prusa MK3, MK4 and equivalent)
• the SMALL can fit on a 180 x 180 printing bed (Bambu Lab A1 mini and equivalent)

Given its size, the SMALL version was proportioned like a ping-pong paddle and can be played as such.
 

The set comes with airless balls in 3 sizes, and 2 wall thicknesses for each size so you can experiment with various filaments and find what works best for you:

• Ø40mm ball, ping-pong size (thickness of 2mm and 3mm)
• Ø50mm ball, mid-range size (thickness of 2mm and 3mm)
• Ø70mm ball , pickleball size (thickness of 2mm and 3mm)

Mix and match the colours at will.

And happy printing!

3D PRINT SETTINGS 
All STL files are already oriented properly.

The Paddles print flat, in diagonal at 45% degress on square print beds, and at about 55% on Prusa 250 x 210 mm beds.
To create the mesh pattern, use 8 perimeter walls and cancel the top and bottom layers (set to 0 layers) and select an infill pattern of your choice. 
The paddles on the pictures where printed with 30% Gyroid infill. 
Less infill and the paddles will be too soft. 30 to 40% should work best.

The handles print upside up with standard 2 perimeter walls and about 30% infill. No supports or brim required.
The fit may be tight or loose with the paddle, depending of the filament you use.
So use some strong glue to fix the two together.

The balls should be printed in flexible TPU to play pickleball. 
(You can try ABS and PETG too, but not sure how durable it would be to play pickleball). 
Hard materials such as PETG or ABS would work best for the 40mm ping-pong ball in 2mm thickness. 
PLA would crack too easily. (I tried with carbon-fiber Nylon and it also cracked eventually).

PADDLES: 
Top layers: 0 
Bottom layers: 0 
Infill: 30 to 40% 
Infill line width: 0.8mm
Wall line count: 8 (for 0.4mm nozzles) 
Layer height: 0.3mm/layer or less if you fancy 
Build adhesion type: None 
Supports: None

HANDLES: 
Infill: 30 to 40% 
Wall line count: 2 
Layer height: 0.3mm/layer or less if you fancy 
Build adhesion type: None 
Supports: None

BALLS: 
Infill: None 
Wall line count: 4 (for 0.4mm nozzles) 
Layer height: 0.3mm for initial layer, 0.2mm above for TPU, can go down to 0.1 for ABS and PETG 
Build adhesion type: 4mm Brim 
Supports: can print without if you go very slow. Otherwise you can add some "tree" supports around the bottom, but not too high so they won't branch inside the ball to support the top arch. That would be hard to remove.
