"Airless" Ping Pong Ball - Table Tennis Ball

Membership Support me a little for $3/month. Thought I'd try this out. An airless ping pong ball! Seen with some of my other ping pong machinations ( https://makerworld.com/en/models/166872 & https://makerworld.com/en/models/207809 ).

Legal weight is theoretically slightly high (based on design program and slicer filament predictions), but I can't feel a difference (and can't weigh down to 2.7g - the slicer says over 3g)

Plays super well! Hasn't broken yet (like my pickleball which takes a little more abuse - https://makerworld.com/en/models/232041 )

Is quieter than a normal ping pong ball, but similar feel.

When putting spin on the ball - the flight is fascinating compared to a regular ping pong ball.

UPDATE (2025_02_04)

Added a print profile for BIQU PLA-HR filament. It is more TPU-like than PLA, but bounces more than TPU filaments that I have tried in the past. The PLA and PETG prints of this ping pong ball have highly variable durability - but this filament is very durable and makes a fun ball.

V2 (2024_03_07)

Beefed up the thickness and opened up the hexagons/pentagons. More durable and better looking.

V1

A little rough at top and bottom, maybe slow it down. But so far testing not showing much changes required in the future. Please let me know.

I tried the scaled profile to use this as a foosball and liked it enough that I worked on designing a more dense airless foosball ( https://makerworld.com/en/models/245307 )
