Oh absolutely. If you can fix the real cause upstream in Blender, do!
Unfortunately as powerful as Blender is, it remains a major offender for producing non-manifold STL files I receive to 3D print - so I would always check its output.
3D builder used an open source engine from the OG Netfabb BTW.

Try opening in Microsoft 3D builder (used to be included in Windows 10, may need to download elsewhere now).
Import, then save as OBJ.
It's pretty good as a fix-all for common issues like this.

#3Dprinting (technically invented in the 1980s but took over my life since 2012)
Google Maps. I literally don't know where I would be without it.
Technology has by and large made life massively better and longer for the average human on planet Earth, overall - despite all the obvious abuse of it.

This is unnecessary and downright evil in either case :(
It's a snake oil vending machine. People are automating the con, and critical thinking is in dire short supply.

And this coming from someone motivated, running a core piece of software in my business on RISC OS... i'm not against diversity in any sphere, but it adds cognitive load to keep up to date across many platforms. Pi OS looks basic on the surface but it's the same underneath and runs on everything.

I believe you and trust your experience.
But that's THE problem Linux has, still, after all this time. I have heard of elementaryOS but wouldn't have named it if you asked me for 5 Linux distros, and if I used it on my desktop it would be subtly different to PiOS on my edge devices - that's work.

I've picked Raspberry Pi OS, because for me consistency between platforms beats any other feature in making a business transition. As a Linux dabbler, maintaining the same trusted, consistent experience from my edge computing as I try to use Linux daily is worth forgoing a polished veneer.

The perennial problem remains: which Linux desktop?
Many are great. None of them quite has the depth of coherence that Windows retains despite Microsoft's best efforts to self sabotage, and to fix this requires a huge amount of unsexy work on the last 5%
Ubuntu or Mint?

Super abundant clean energy would solve a LOT of problems, and it's already possible with the political will.
As a first step we need to decouple energy unit costs from the futures market for fossil gas, so that people and companies are incentivised to literally make hay while the sun shines.

Yes it does, thanks for sharing!
My reason for interest is that I already had the idea to adapt my own Braun hair clipper which uses very similar design, to include a vacuum cleaner hose take-off. If and when I get around to finishing that I will share it back!

Awesome. Did you design it or download the designs, either way could you share a link please?
