We are so excited to announce the talks and workshop schedule for #OHS2026! Check out the lineup and see who is joining us from all over the world to talk open source hardware and maybe even register for one of the incredible workshops we'll have running on Day 2: 2026.oshwa.org/schedule/
I wish I had his talent but I'm another Greg Saunier :D
What did I sidetrack myself with completely today? well, you see... My logitech C920 webcamera is UGLY AS FUCK. aka stock. Cute right? printing a test fit jig currently.
I was lucky enough to get a quick glimpse. UI is easy, smooth and speedy.
While FFF goes close source the resin industry goes open source!
I love designing and making these 3D printed organizers. Low effort, huge reward. Am I weird?
CAD+3DPrint feels like a super powerñ

Oh that's interesting! Were they under 3k$?
Oh nice to hear! It seems to be a "small team based on Georgia USA" according to there GitHub.

preFlight logo. Similar to the Slic3r logo but with light blue and orange color and a rocket crossing it.
Showcase of the Athena perimeter generator compared to Arachne. The perimeters are better filled and more regular.
Table comparing Brick Layers with interlocking perimeters. The mechanism of this new slicer is based on X/Y variations and over-extrusion to compress plastic between the voids while. Brick Layers is based on Z variation. It claims 5 to 15% strength increase.
preFlight is a new open source slicer based on #PrusaSlicer but with deep rework of its internals.
- Truely 64bit
- GCode processing in memory
- Athena algo improving over Arachne
- Interlocking perimeters similar to brick layers
- Deeper #RRF integration

Can you do firmware upgrades offline now?
@infomaniak.bsky.social maybe you could help?
I think that's a good approach, better independence and maybe closer to the clients.
I see, I've never sold something on those platforms. Thanks for sharing your experience.
Why you think this acquisition is not good?
I appreciate this approach:
"MyMiniFactory has adopted a zero-tolerance stance on AI generated content on our platform."
MyMiniFactory has acquired @thingiverse.bsky.social . Hopefully that makes it independent from a 3D printer brand (it was an UltiMaker product). I hope they will now add CERN-OHL V2 license, the only license that support 3D printed functional hardware.

Yep and good to mention it as well.
Oh yeah, and we have been many to ask Printables. I personally also asked Thingiverse and Cult3D and none have added this license. And this is now the most used hardware license from OSHWA certified projects: michaelweinberg.org/blog/2025/10... (section "Hardware Licenses")
They are also hiding the "Meets open definition" for the OCL, lovely isn't it?

Yep exactly my point, I don't care about their products and vision, but misleading all the time confuses people and damage the open source community. I am tired to have to redesign from scratch every supposedly open source designs I download because the source is missing. This is useless.
You see all those little things that are damaging the open source in 3D printing.
Oh yeah, it was obvious this would come. Also we have been many to ask them to add CERN OHL V2 license, which is the only one compatible and designed for functional hardware. APrusa has always refused. I also asked twice Thingiverse and once Cults. Still nobody get it 🤦 . ⤵️
They know very well what they are doing. I don't care about Prusa, I care about the damage this is making to the open source community. Everytime I download a file from someone else that is supposedly open source I have to redo it from scratch because the source is missing...
Screenshot of a Github issue comment saying: I noticed on Printables that the license does not show the "Meets Open Definition" summary detail like almost every other license, presumably since it would be silly to show "✖ | Meets Open Definition" when selecting a license with "Open" in the name.
Really they are playing all possible silly games 👎

I wish I could stop writing those posts seriously. But apparently we still have 90% of the media that continue to copy their words without a quick search on the topic.
Oh BTW, the CAD files are just like STEP files, nothing more and certainly not a source.
Screenshot of a promotional email from printables.com that mention that the Core One is open source with to OCL license.
Later in the email they once again write in large bold font "Open-sourcing CORE One/L CAD Files".
And Prusa continues, so disrespectful 🤮. Flagged by so many people for their wrongdoing, yet they persist in trying to redefine open source for marketing purposes. Champions of open-source-washing!
➡️ The OCL isn't an open source license

Thank you Dave for all the great and hard work. Thank you for having trusted my work and sold many Bear frame kits. I wish you all the best for the next steps 💫

Guess who is once again displaying their ability to hyperfocus on being a hater?
It's me, I spent all evening writing my own compilation of all the reasons I think AI sucks so I can post it under genAI-made FB posts.
Work-in-progress, suggestions welcome!
