Present to you V1 of Airless Ping Pong Ball ! The design was created to match international game regulation - mass of 2.7 grams (0.095 oz) and a diameter of 40 millimetres (1.57 in). Altough the mass is still 10% off, coming in in 3 grams, the bounce is actually really similar!
Please do Print it with some stronger PLA, like PLA tough or super PLA+. A strong ABS/ASA is also a good choice, but a more rigid material will work better.
Currently working on the model so it works better with a bigger variety of less strong PLA's.
Thanks to your amazing help and feedback, version 2.0 is now up! Slight adjustments, Big results, check it out! - https://makerworld.com/en/models/376178#profileId-276163
