Just take a moment to read through this. It could also be due to your workflow.
I can summarize it briefly: If you save the 3D models to your computer first and print them later, they often aren’t counted. Also, you have to reach a certain number of print hours per month.
Because of this, I haven’t received any Boosts since April 2025. I meet the hour requirement, but don’t print directly from the website or app. I download the 3D models from MakerWorld and print them later.
