Do not have an ability to buy a set of table tennis paddles and a ball? No problem at all. You can print one at home:)

Entertain yourself without the need to go out for shopping.

Print instructions

Paddle:
Layer height 0.2-0.3mm.
Infill 10%, perimeters 2, top/bottom layers 3.

Ball:
Layer height 0.15mm
Perimeters 2, detect thin walls.
Speed: ~30mm/s or slower

Paddle has a tight fit after printing. Just push the pins inside while pressing to a table. This is on purpose, no way to disassemble without braking.

Ball is intricate part, should be printer slowly. Tested few versions but the best one still requires glue (shown in pictures). Played whole day, ball is still holding strong.
