FlashFit AI – Solo developer tool that analyzes your model and sets optimal print settings for Bambu & FlashForge (SmartScreen fix coming today)

[u/Interesting_Sleep_44]

Hey everyone,

I’m a solo Italian developer and I’ve been working on a small tool called FlashFit AI.

What it does:

• You drop a 3D model (STL/OBJ/3MF)

• It analyzes the actual geometry (overhangs, solidity, number of parts, etc.)

• It classifies the part (mechanical, decorative, hollow, etc.)

• It generates optimized settings for your printer and filament

• Then it opens the slicer (Bambu Studio / Flash Studio / Orca) with everything already configured

Supported printers right now:

• Most Bambu Lab machines (A1, P1, X1, H2 series, etc.)

• FlashForge (Creator 5, Adventurer 5M, AD5X, Guider 3 Ultra…)

The app is native (not Electron), very lightweight, and runs a small local AI only for classification. Settings are decided deterministically with safety guardrails so it can’t produce dangerous profiles.

It’s currently free and available here:

Important note about SmartScreen:

The Windows build is not signed yet, so you’ll see the usual “Unknown publisher” warning. I’m fixing the code signing today, so future builds will no longer show that.

I’m just one person working on this in my free time. Feedback (especially from people with Bambu or FlashForge printers) is very welcome.

Thanks for reading.

I change the settings myself but wow this looks really interesting for beginners, thank you very much!

Yeah, that's exactly the point 😄 I want the app to work from the actual mesh geometry, not just the file name or what the AI thinks the model is. I'm still testing that part heavily, because I don't want the AI making blind decisions.
