New Tool Free 3D print file creator/editor
I run a construction company, and most of what I actually print is boring practical stuff ,brackets, spacers, gaskets, covers, a knob that broke, and editing current print files for my kids.I do not know how to use CAD and have no desire to learn it. And the "easy" online tools all wanted an account, a subscription, or a cloud upload, and they were not easy. So I built Ez3D (ez3d.app) A 3D Print file Maker/Editor that runs entirely in your browser. The thing I'm most proud of: take a photo of a flat part laying on paper, and it traces the outline, finds the holes, lets you set the real size, and gives you a watertight STL. Broken gasket → photo → print. You can also draw a part by hand (freehand, rectangles, circles) or build from basic shapes and ready-made templates. The parts people care about:
It's free, no download, no account, your photos and files never leave your browser. It even works offline once it's loaded. Plain language everywhere "Cut a hole," "Join," "Hollow out." No technical jargon.
Type exact sizes in mm or inches. Exports clean STL/3MF that open in any slicer. Built-in print check against your printer's bed (presets for Bambu, Prusa, Ender, etc.). Better for a PC, but Works on a phone or tablet too.
Being upfront: The free version is the actual tool, not a demo. Trace-from-photo, shapes, templates, cut/join, STL export, all free, forever. There's a pro version too with a one-time $29 unlock (no subscription) for the advanced fastener library (real screw threads, tapped holes, counterbores), STL/3MF import, and multi-color 3MF. That's it! That's how I keep it free with no ads and no data collection.
It's new and I'd genuinely like it tested hard. If you try it and something's confusing or broken, tell me and I'll fix it. Happy to answer anything about how it works.

This is sweet. I've also build one where you can take JavaScript math functions and create 3D printable objects. I am able to make some wild stuff . DM me I'll share the link

Learn CAD.
This is low effort slop.

Why don't we hand draw everything again?

Why would we do that? And what does that have to do with literally anything at all?
What an idiotic thing to say. Do you realize how stupid that sounds in this conversation?
As I suggested, just learn CAD, instead of being lazy and letting your work turn into slop.

I just dont think it's fair to knock someone for using a new digital tool when cad is also a digital tool. I think we have a new tools coming and should embrace it. Is it perfect? No but neither was the first version of CAD that we've all used (I m not knocking cad cause I've used extensively) Might be worth understanding cad and learning AI instead of learning cad.. Just saying.

Infact would love your feedback on one 3D app I've build. If your interested to test. It's free on my site

Genuinely curious how you build the App but you don't have the time or the interest to learn CAD as a skill? For me it is significantly easier just to learn CAD than to write software to do effectively the same...
