Bsplat with soluble supports. Does not print or look as good as your previous efforts, but bounces much better. Thank you.

Could you please share more specifics for what settings worked best for you? Such as layer height, etc. Thanks.

Can anyone tell if this would be compatible with the forerunner 55?

Edit: I was able to make it work, by flipping the top 180° and lowering it by 1.6mm, effectively removing the two bumps. (edited)

Printed in PLA for my girlfriend's Venu 2 Plus.
A nice design - the top is pretty thin so in my case, it came out somewhat transparent (which I deem interesting and not a problem).
Did not have the screws, therefore I used a little bit of superglue.
Tolerances for the angled charging port are very good - barely any movement (which I like a lot).
Might try in PETG or ASA later.
Thanks :)

These hinges are terrible. They are fused together and will not separate to actually be a hinge. I've broken two of these that I've printed in an attempt to get the hinges to actually do what they are supposed to do.

The hinges didn’t work for me, similar to what the previous comment mentioned. I printed with a 0.16 mm layer height using a standard 0.4 mm nozzle. If this model requires a 0.2 mm nozzle or other specific print settings, that should be clearly stated in the description.

Old: Only one fix stl. Not printable

With some adjustments below, possible but inconvenient (edited)

Great box, thank you! Works perfectly and printed great!

Kimya PEBA-S has insane energy return, credit to Make It Lab on YouTube for sharing this material with me. I think with some tuning of this model we can reach NCAA ball standards easily. Material properties bring this full size model just over 500 grams printed, so there’s a big margin to thicken the hexagonal lattice panels to improve bounce in those areas. Bounce is excellent, I think I’m exceeding the NCAA 1200mm minimum bounce height from 1800mm (6ftish), but only when contacting the rib hubs. Need to tune my settings more for improved lattice overhangs and print another one.

I don't have TPC (and don't even really know what it is) so I printed another in regular old PLA since they are only display pieces anyway. Why do I keep printing these? Who needs seven 3d printed airless basketballs? I don't know, just don't tell my wife how much money I've spent on filament on them!

This is my third attempt. This one is 50% size white PLA. I used supports this time instead of a brim. The print turned out beautifully, but man that support is hard to remove!

Bounces nicely with Overture pla +

Great model. Printed at .12mm layer height, PLA 15% gyroid infill. Took 96hrs to print. Thanks for a great model.

Airless? How do you keep the air out with so many holes?
Looks like a wiffle ball, circa 1953.

Printed with Inland TPU (stiff) and I was really struggling with it moving while printing. Came out rough (my own fault not the model). Works well when I want to throw it at coworkers though!

This is awesome. Printed in TPU, and scaled to the max build volume of my A1 Mini. It took almost 40 hours, but well worth it for an awesome (and less expensive that Wilson's) display piece. Doesn't really bounce, but it's one of the cooler things I've made thus far.

Printed at 50% scale with Duramic PLA+ and it bounces great! I flattened a small portion of the bottom so it could be printed with little support. Just added a few tree supports on the sides to make sure it didn't move. As a bonus this allows it to sit on its own without a stand.

The attached picture is an animated GIF so you can click on it to see it bounce. :)

Update: Well it ended up breaking after about 50 bounces. To be expected I suppose but it held up fairly well for a while. (edited)
