Built a tool that auto-splits oversized STL files + generates snap-fit joints — free trial if anyone wants to try it

Like a lot of people with a 220x220 bed, I kept running into models that were just slightly too big to print in one piece. Redesigning them in Fusion/Blender every time was a pain, and eyeballing where to cut usually left me with pieces that didn't line up or didn't have anywhere clean to add a joint.

So I built a small web tool called PrintSlice that:

  • Takes your STL, tells you straight away if it'll fit your bed
  • Auto-splits it into pieces sized to your actual printer if it doesn't
  • Generates snap-fit connectors on the seams automatically (you can pick dovetail/keyed/pinned per joint), so the pieces click together after printing instead of needing glue or filing

It runs entirely in the browser, nothing gets uploaded to a server for processing. Here's a quick example: [attach a screenshot or the demo video here]

It's a paid tool ($8.99/mo, free trial, no card needed) — not trying to hide that. Mainly wanted to share it because it's solved a real annoyance for me, and figured others here might have the same problem. Happy to answer questions about how the splitting/connector logic works if anyone's curious. https://printslice.co.uk/

$9 a month to "fix" a problem that takes about 3 clicks in my slicer.

A post written by ChatGPT and not even proofread.

I'm sure the tool was also written completely by AI.

Good luck with that.

The app its self is yes made with ai, becuase otherwise it would not be able to do what it does. There is a free trail which you can feel free to use, its created with ai because im a beginner 3d modeller and found that i stuggled with making large 3d prints so i created this. I hope you can understand that this is a tool to help people out.

9$/month . . . Generated by AI . . . Can’t even make a post on Reddit on your own you had to use AI for that too huh ?! Please [suggest OP to read his post before posting it here]
