My apologies for the stupid and selfish mistake I made and the harm I have caused

· 2 min read

I'm writing this post to apologize to Gina Häußge, one of the most important and respectable person in 3D-printing community, as well as to the OctoPrint community for the stupid and selfish mistake I made and the harm I have caused:

I created a script to manipulate the OctoPrint stats to boost the ranking of Obico for OctoPrint plugin, probably back in 2022, after having some suspicion that OE was doing that.

I have left the script on auto-pilot for a long time now since Obico pivoted to working on the nozzle camera AI early 2023. When Gina told me about what she found out about OE, I should have had the gut and ownership to make this confession at that time. I guess I was feeling opportunistic since I was quite sure the script had been long dead.

But this is not an excuse for not being forthcoming with you and betraying your trust. Nor does it serve any justification for the stat manipulation script. I did the wrong thing. By doing so, I caused a harm to the OctoPrint community, as well as exhorted an emotional toll on Gina, the one I respect the most in the 3D printing community. And I should bear the consequences.

I have now made sure the script is truly stopped. And I'll be happy to work with you to make it right for the community.

My sincere apologies again for such a stupid and selfish mistake.

Tolerance Test in OrcaSlicer: A Comprehensive Guide

· 9 min read


3D printing has revolutionized the way creators, engineers, and hobbyists bring their ideas to life. However, the transition from a digital model to a tangible object isn’t always straightforward. One key challenge is ensuring parts fit together seamlessly. In this comprehensive guide, we’ll delve into the world of tolerance testing using OrcaSlicer, a valuable tool for 3D printing. We will understand together how to know the right tolerances value to design successful prints which fit together well.

Tolerance Test in OrcaSlicer: A Comprehensive Guide

But before we get started testing our 3D printer, let’s understand some important related topics.

The Importance of Tolerance in 3D Printing

In the world of 3D printing, tolerance is all about precision. It's the measure of how accurately a 3D printer can replicate the dimensions specified in your digital design. Imagine you're creating a puzzle; if the pieces are too big or too small, they won't fit together. Similarly, for 3D printed parts to function and fit together as intended, the printer must be able to accurately produce parts within very tight dimensional limits. Good tolerance affects everything from how smoothly moving parts interact to the overall look and strength of the finished product.

But why do you need to make the tolerance test?

Well, in 3D printing things do not always go right. Every filament type has its own shrinkage coefficient and this affects how your print turns out. Different printers, with their unique mechanics and settings, can also produce varied results. That's why testing for tolerance is crucial - it helps you understand how your specific printer and chosen filament behave together, allowing you to adjust the tolerances in your design for the perfect print.
