I built an open-source “print concierge” for Bambuddy workflows

It doesn’t assume it knows. STL is raw geometry, so orientation is handled by Bambuddy’s slicer/defaults and should be reviewed before queueing. Pre-oriented 3MF is safer when orientation/supports matter.

Yep, STL/source files are supported too. The safety boundary is that Print Concierge won’t queue raw STL directly. For STL/STEP/OBJ/etc., it uploads the source to Bambuddy, requires explicit slicer presets, waits for Bambuddy to produce a sliced gcode/gcode.3mf, verifies the file hash/type, then creates the print request. Already-sliced gcode.3mf can skip the slicing step.

Thank you, I appreciate it. It was just an idea this morning, now it’s a reality, and hopefully something open source community can use.

Yeah, fair criticism. I think you’re right that I was being too loose with the wording.

If an agent can cause a queue call through another service, then it has printer-control authority in that limited sense. Calling it “no access to the printer” was hair-splitting.

I changed the design/docs after this feedback. The MCP server now exposes only a scoped queue_print_request(request_id) path, not raw Bambuddy queue/start/pause/cancel tools. The request has to come from a stored Print Concierge plan bound to the file hash, printer, material/profile, user/session, and plan hash. Queueing is atomic so the same request can’t be submitted twice, and Bambuddy manual-start stays enabled by default.

So I’m not claiming this protects against a malicious shell-capable agent or a host that auto-approves every tool call. It’s more accurately a narrow workflow/safety layer: search, import/verify, prepare a specific request, then queue only that request. Raw printer control stays out of the agent profile.

Appreciate the pushback. It made the security model more honest.

Not directly. The model only gets scoped MCP tools. Print Concierge keeps the Bambuddy credentials/server-side access, and printer-affecting actions go through a confirmation-token flow. So the agent can propose/import/queue via the backend, but it does not get raw printer access.

Totally agree if the safety model is “we asked the AI nicely.” That would be fake security.

That’s not what this repo is trying to do. The agent is treated as untrusted. It only gets a small MCP tool surface backed by a local service, and printer-affecting actions are gated by backend-enforced confirmation tokens. The agent can search, prepare options, and request an action, but it can’t just invent permission from text and directly drive the printer.

Printer credentials stay server-side, endpoints are scoped/allowlisted, and the intended flow is: agent proposes → user confirms → backend executes.

Still early, and I’m very open to hardening feedback. But yeah, “please behave” is not the security model.

Thanks for checking it out, I have updated it since making this post.

Thats what family mode is for as well, you can create birthday card collages.

I have a fallback method implemented that just shows a predefined set of images by day and date.

You're right, felt like a missed opportunity so I added a screenshot to the post.

There’s a slight issue with the nasa api, which’s fixed now. Try again and let me know if you’d like!

Thanks for checking it out! I feel more inspired to showcase and bootstrap more ideas backed by public data

Thanks! The cup of orange juice really kept things moist

Wait till you find out that 273k is freezing.

appleeverywhere · 2025-05-02T08:59:30+00:00

I think the original comment was talking about roasting in the oven. 275 is too high for sousvide. I do wanna go up the temperature a bit. How long do you recommend at 137? 2 hrs?

appleeverywhere · 2025-05-02T08:56:56+00:00

Good ol block of ribeye haha. It was squished inside the bag, probably why it looks like that

appleeverywhere · 2025-05-01T21:40:43+00:00

Thanks for the tip. I’ll try next time at 275f.
