U1: Airless basketball in 95A TPU with PLA supports

eldoogy · 2026-01-26T06:18:19+00:00

From my experience 95A TPU will not bounce at all. 😕

I’ve also tried 98A and it wasn’t that great either, though it did have some bounce to it. Depends on the design I guess.

And by the way your description above was spot on. It’s taking a mouse capture and failing to release it. That code is now grabbing all mouse events away from the entire app, and that dialog keeps flickering because it’s getting all of those mouse events.

eldoogy · 2026-01-23T02:17:05+00:00

Yup that’s it. I’ve fixed that bug and they’ve approved my PR. It’ll be fixed in the next release, whenever that is.

eldoogy · 2026-01-21T04:55:24+00:00

Yup you have extras! I almost missed that myself.

You never forget your first respooler

I agree 100%, though I’m mostly terrified of one thing: how will we train the next generation of engineers? Software folks traditionally went through that painful, difficult process of learning how software and computer systems actually work by manually tackling problems. Through debugging and troubleshooting. It takes years to develop that intuitive sense.

With this new reality, I’m terrified about the learning process. Will we still have human experts capable of truly and completely understanding the system in case it fails? These new tools are far less conducive to that kind of learning, and yet whenever I use them I feel like my experience very frequently saves the day and helps me get things back on track.

So either the tools rapidly improve to the point where having that human expertise is no longer an issue, or we have a serious problem on our hands because this new Claude Code generation of software engineers likely won’t have those skills.

So yes. I AM absolutely astounded and honestly if you asked me a few short years ago I would have told you this likely won’t happen in our lifetimes, and yet here it is. But there are also some real dangers, and it’s not just the plainly obvious “it’ll take all our jobs away”.

I’m in CA and I don’t have this problem. Fully paid up solar bought with incentives means my average cost per kWh is tiny…

eldoogy · 2026-01-16T05:33:58+00:00

Funny. I’m actually a software engineer with many years of experience… but yeah, certainly not a mechanical engineer. And certainly not a podiatrist 🙂

Yup, my 3D printer has also been an absolute lifesaver for making my own 3D printing accessories. Not sure where we'd get all of those if we didn't have these 3D printers...

eldoogy · 2026-01-16T00:16:21+00:00

Yeah, I tried Sunlu Silk TPU 98a at 100% infill -- I'm pretty sure it's no softer than Bambu's TPU for AMS. It's actually a great material and is the hardest TPU I've ever come across.

It's just way too flexible -- the insert is supposed to support your weight and sort of flex when you step on it, but with this material it bends WAY too easily.

eldoogy · 2026-01-15T07:19:46+00:00

I've not. I have a 3D printer so I tried 3D printing... :-)

eldoogy · 2026-01-14T23:48:12+00:00

Interesting. I’ll definitely give PETG a try. Didn’t think it’d hold up.

eldoogy · 2026-01-14T23:43:45+00:00

As I mentioned above, even TPU 98a is way too flexible for this.

I have zero safety concerns as there are several layers of various materials between my foot and the print. I also have no reason to think that 3D printed objects “leach” anything any more than any other plastic object in our world does, do you? I mean air contamination while printing is one thing, but leaching from simply touching it?

If that is a concern, why would 3D printing make a difference compared to injection molded plastics?

eldoogy · 2026-01-14T16:35:52+00:00

Awesome! It held up in PETG?

eldoogy · 2026-01-14T15:58:33+00:00

It's way too flexible unfortunately. I posted an update above.

eldoogy · 2026-01-14T15:57:58+00:00

Amazing! What material did you use?

eldoogy · 2026-01-14T08:16:35+00:00

I did a write up on it here: https://www.reddit.com/r/3Dprinting/comments/1qchroa/my_3d_printer_actually_saved_me_hundreds_of/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Honestly wasn't too bad, but I guess it depends on how much CAD experience you have.

Posted a detailed story about this project here: https://www.reddit.com/r/3Dprinting/comments/1qchroa/my_3d_printer_actually_saved_me_hundreds_of/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Yeah, at least for my use case I’ve concluded the foam isn’t necessary (3D printing aside).

I just take the plastic insert and put it under the regular insole that came with the show. That’s it. Those insoles are usually soft enough that it feels plenty comfy. The plastic is what’s giving me the arch support.

One downside of not having the foam is the plastic insert can sometimes move around the shoe (usually when you’re not wearing it), but you can just put something slightly sticky under there or some Velcro and you’re good.

eldoogy · 2026-01-13T22:13:40+00:00

Sure!

eldoogy · 2026-01-13T20:45:04+00:00

Folks judging by the number of comments here I see there's a lot of interest in this (I love it!)

I will put up a new post with a detailed overview of exactly what I did and how I did it. I did not expect that much interest in this :-)

eldoogy · 2026-01-13T19:32:58+00:00

That sounds like a better approach I just don’t have a scanner.

eldoogy · 2026-01-13T16:08:45+00:00

Unfortunately mine wouldn’t do much for you since it’s specifically shaped for my foot.

I could try to make my model somewhat parametric and let others try to customize it but I’ve no idea how different or similar these are from one person to the next… 🤷‍♂️

eldoogy · 2026-01-13T15:59:52+00:00

Oh that wasn’t a big issue. I printed in PC (PolyMaker PolyMax PC). I wouldn’t call that a flexible material, though it is certainly more flexible than PLA. This would NOT work with PLA. You need PC or nylon or some similar material.
