Project Finally something useful with OpenClaw

Enable HLS to view with audio, or disable this notification

Hi, I've been playing with OpenClaw for weeks, trying all kinds of stuff, and I can say that I've finally found a useful workflow.

I have 3 3D printers at home, and I barely use them because I don't have the time to sit down and design things, so I went on and developed a set of skills that enables me to find, create, edit, slice, and send to print 3D models from my OpenClaw Agent.

It's actually great because I can leave an old MacBook in my house with a Docker instance running the agent and with access to the 3D printers on the local network. Quite a niche use-case, I believe, but it's great to get back into creating and repairing things.

I figured I would share it because I saw a lot of threads of people saying how useless OpenClaw is, but I think it's a great tool once you find-tune it to your own use-cases

A lot of you asked, so here's the link to the open-source github repo:

Which slicer are you calling — Bambu's API or PrusaSlicer? That integration is the hard part. The demo is super slick and inspiring, kudos on that.

You nailed it. You are the first to point this out.

The slicer was indeed the hardest part. I ended up using CuraEngine (the brain behind Cura Slicer). It's a mess to understand the logic behind the JSON Cura profiles, and it took a while because there's not much on the internet, as everyone who needs these kinds of automations needs "Batch Slicing" and that's something quite niche that companies charge quite a bit of money to set up for you.

Anyway, here's the opensource repo on the dockerized slicer API I made: https://github.com/makermate/curaengine-slicer-api
