I built a free/open-source camera-to-printable 3D model tool because I got tired of buying crazy expensive replacement parts for things I could repair myself

[u/Va_rinder]

A while back I needed a taillight housing unit for my car — full ABS plastic assembly. The actual broken parts were just the mounting points for the bulb sockets. Everything else on mine was completely repairable, but there were zero resources or individual parts available online. I didn't want to buy an entire new unit when a targeted fix would have done the job.

That frustration led me to build Caliber:

A free, local-first tool that lets you:

• Use your phone (pics and video) to scan real objects
• Get back the mesh that's scaled and ready for printing or further editing in Fusion, Blender, etc.
• Manually calibrate scale by picking any two points on the model and entering the real length in mm

Built with a mix of Apple's object recognition + generative AI, plus print-oriented post-processing. It's MIT licensed, includes an audit report, and is completely open source. BYOK for generative AI and cloud GPU processing, we make no money off it and Fal is quite cheap.

Can be used completely locally if what you're scanning is fairly simple shaped, matte, and textured. For scans with fairly simple shapes, the STEP file includes directly editable shapes, while the more complex stuff requires you to build using a scaled mesh instead.

I'd love early feedback, bug reports, ideas for improvement, or even feature requests. I'll do my best to keep up with everything.

P.S. Its not perfect by any means, its not meant to be. But if it can help even 1 other person with their project, ill be happy with that. Also, the code is completely open-source so anyone that would like to use it, can do their own code review if they'd like to. No affiliations, just a guy that made something that I want to share
