3DPrinting

Ceci n’est pas un Mac mini. 🎨

As Magritte might have said, appearances can be deceiving.

It may look like a Mac mini, but it’s actually a Raspberry Pi 4B in a custom case I designed and 3D printed with my Bambu Lab A1 mini.

And, of course, it proudly wears the NetBSD logo.

Who needs a Mac mini when you can have a little NetBSD box of your own? 😄

Building pieces for the 3D printer using the 3D printer reminds me using a compiler to compile a compiler

My new addiction

Today, a friend sold me his “old” 3D printer, and a whole new world opened up to me.

And yes, my instance just got a little prettier.

@freecad@social.freecad.org Late to the party, but was done exactly on #FreeCADFriday 😅.

I was asked to make a replacement part for a broken clip that is needed for a cake box to secure the lid to the metal sheet.

Printed in yellow PETG, one Original part was still used.

@freecad@social.freecad.org A hobby project I’ve been using daily for a few months now: murmurglass.

It’s a mic with a proximity sensor that acts as an automatic push-to-talk trigger for the Handy dictation app. Bring it to your mouth, and it holds the virtual PTT key; put it back down, and it releases it. I don’t need to touch the keyboard at all—just grab the mic from the desk, speak, put it back, and the text is instantly pasted at the cursor. It saves a ton of keystrokes, which is a huge relief for my sore hands.

Modeled in FreeCAD and printed in ABS-GF4. Inside, there’s an ESP32-S3 with an INMP441 mic, an APDS-9930 proximity sensor, and an MPU6500 IMU. It spoofs a USB keyboard and an audio interface at the same time. The hardware is also there for gesture recognition, though I haven’t finished the code for that yet.

… und zum Schluss: Der Nutzegegenstand. 😂😁😊🫣

Falls ihr Euch jetzt fragt, wieso ich die nicht einfach auf den Tisch stelle:
Da stand sie immer, aber ich habe sie ein paar Mal umgestoßen, obwohl sie außerhalb der normalen Fuchtel-Reichweite stand. Und ich brauche den Platz jetzt für einen kleinen Scanner.

… dann die Nut nutzen um dieses putzige Zylinderdingsi anzustecken… 😊

… dann an die Tischplatte anschrauben… 🤔

Hier sieht man auch nochmal die hässlichen Ecke, die sich leider beim Drucken von der Platte gelöst hat. Stört aber die Funktion nicht.

@freecad@social.freecad.org This #FreeCADFriday I did a cut and shunt operation with the BoxTurtle hub and the encoder from the #ERCFv3 to create a hub with encoder for my #BoxTurtle MMU. This enabled me to add the encoder hardware from the ERCFv3 I am replacing directly onto the BoxTurtle, giving me clog protection which I was missing since retiring the ERCF MMU. #3dprinting

@freecad@social.freecad.org Since the mount for a bike light didn’t fit on an aero handlebar, a 3D-printed solution had to be designed.
Already tested (printed in PETG). 👍

… und der Knubbel wird auf die Schraube draufgeschraubt…

Hat jemand aus der #3DPrinting Community Erfahrung mit Filament Recycling? z.B. Recyclingfabrik

Ich habe hier PLA Reste und überlege die zur Recycling Fabrik zu schicken, aber selbst mit Gutschein durchs recyceln kostet das recycelte Filament bei denen ja mehr als neues anderer Anbieter. Taugt das recycelte Filament?

… dann wird die Schraube durch das Dingsbumsi durchgedreht …

… und dann noch so ein u-förmiges Dingsbumsi…

I can see why #3MF (despite having been presented as the STL successor due to its flexibility and expressivity) is not used more often in the maker space.

Every time I take a deeper look at the readers and writers I programmed for the Slicer I end up finding new “subtle” flaws.

Having many versions of 3MF, many versions of the underlying OPC spec, and also “spec extensions” doesn’t help.

Look, I just wanted to update the zip dependency because of its security-related fixes… and then I made the mistake of asking myself what encodings were allowed for the “part names”.

Rabbit hole it is, again.
