Started generating little QR code stickers for my 3D prints, which connects them to a database with all kinds of metadata: the printer it was printed on, the filament that was used, as well as the specific print settings. May even add the actual gcode eventually.

@fribbledom nice idea, i've been contemplating something similar. I even looked at filament which can be laser engraved ;-)

@fribbledom I think we should make something like that mandatory on so called devices.
The QR code should point, among others, to the source code respository of whatever the device is running.

@saper @fribbledom Yes! But also like user guides and manuals etc.

A lot of people don't know how their stuff works because their partner was the one to install it. But they might recognize a QR code, and get curious.


It's doing exactly that ("connects to a database")... it's essentially just a URL pointing to an interface where I manage all the stuff.

@fribbledom @ekaitz_zarraga with my good sight and ultraclear screen (ironic) I thought it was cheese with a QR printed. On the cheese.

🤦‍♂️ 😅

@fribbledom this is a really cool idea!

(And of course I checked ;) )

@fribbledom I'm introducing this to my D&D group that has gone totes nerd on 3d printing & all the possibilties. Could be super useful for keeping track of beasties on the board.

@fribbledom I love that idea. Curious what you're thinking for the backend. (And you really should've taken the opportunity to rickroll (; )


I've started writing a little Go backend, which stores the data, provides a little restful API to query it, generates the QR codes & prints them. I run it alongside OctoPrint on my Pi.

Cura / PrusaSlicer plugins on the other side, talking to the backend.
