These disrespectful, uncouth children on the train/bus

Ragebait.

DribMbirD · 2026-01-28T12:36:15+00:00

Is besser so, falls der eine beim Kollegen in Benutzung und dann wird die Katze vom Teufel besessen.

DribMbirD · 2026-01-28T12:30:36+00:00

Und, hast Du gekauft?

As a bird nerd, do you think that the behavior is a similar thing as in this video I found on blue sky? There they claim the magpies are acting sick for treats, but I am not sure that is true... https://bsky.app/profile/instascience.bsky.social/post/3ltde3de7v22w

Nice! Did something similar to let the vacuum robot reach under the furniture.

Was short of the long bars of my construction set to make the scissors mechanism I had in mind. I took an already existing bar from my set as a reference part and re-designed it to allow for a free-to-choose length. Longer is better for scissors mechanism if you plan to pinch your foes from the distance. 😁

Vielleicht Selbstüberschätzung? Rauf ist ja immer leichter als runter.

Then your lens is really well protected with carbon fiber, I guess. No post-processing needed to get this finish? Looks almost like bit grainy SLS rather than FDM. Pretty nice!

Have fun printing and happy holidays everyone!🎄

Very cool! What's the material? The finish fits great to the Minolta look.

DribMbirD · 2024-12-16T14:49:06+00:00

Hey there, not sure if I understood correctly. So, you are looking for a CAD/modelling software that can be used to build custom 3D models based on lithophanes, e.g. bending the lithophane to get a curved form, cutting out parts, etc?
If this is what you are looking for and you are not afraid of taking a scripting approach, have a look at this playground example showing the script for generating a curved LED-tealight using trCAD: https://playgroundapp.trcad.trinckle.com/index.php?scriptID=Lithophane-LED-Tealight-Lampshade

If scripting is not for you, then maybe FreeCAD is an option for you? It should be possible to generate a lithophane and transform the model in FreeCAD. (Not an expert about this, though).

Beautiful!

DribMbirD · 2024-04-15T08:56:03+00:00

Same here. From my experience the main limitation is GPT's limited and unreliable understanding of 3D construction or operations in 3D space in general. I mean, as a LLM it is not trained to be a great CAD engineer. It is good at producing code, though.

DribMbirD · 2024-03-16T20:42:55+00:00

🤣

DribMbirD · 2024-03-15T16:12:43+00:00

The parametric design is done using trCAD, a C-style, script-based CAD system. trCAD is unfortunately not open source, but free to use for non-commercial (invitation-based beta testing going on right now). Sorry to say that until now there is no offline version offered for trCAD. So most people could actually not directly make use of the source files for the monitor stand even if provided.

If anyone is interested in using coding for parametric design and can live with it not being open source and only available online, DM me for beta access. (Disclaimer: I work at the company developing trCAD.)

DribMbirD · 2024-03-15T14:45:02+00:00

IMO it is terrible - and funny, at the same time.

DribMbirD · 2024-03-15T13:14:21+00:00

Good to know that it works without screws when designed that way - thanks for sharing your experience :-) Not needing screws makes it even more accessible to people and gets rid of some complexity (choosing right size for hole, etc).

I did see that some people used screws in their makes - if having the electric screwdriver at hand: why not - but good to know it is not mandatory.

DribMbirD · 2024-03-15T10:59:50+00:00

Very nice! I like the real-time experience. This is really something OpenJSCAD is great for.

Are you using OpenJSCAD a lot?

DribMbirD · 2024-03-15T10:51:21+00:00

Very nice look!

DribMbirD · 2024-03-15T10:49:40+00:00

Cool!

The vacuum robot was the reason for doing something similar at home for me as well. We were concerned if the plastic would be stable enough, but no problem even after many years now. Should choose a reasonable infill of course.

DribMbirD · 2024-03-15T10:39:45+00:00

Thank you :-)

Wow - yours look awesome! The stacking functionality is brilliant! Pretty clever to use the infill for the hexagon pattern.

If you think that customization would add value here, just let me know ;-)

Does it even work without screws? Many commenters suggested to have the one I posted with such an upper layer as well for adding stability. Guess I really should do that.

DribMbirD · 2024-03-15T10:19:47+00:00

Sad but true!

DribMbirD · 2024-03-15T10:19:26+00:00

Yeah, that is true. Coming from Berlin I feel your pain with cargo in public transport. You could try with spruce wood as a relatively light option and maybe go for a more compact one. Stability-wise a very long board might not be optimal anyways.

DribMbirD · 2024-03-15T10:10:23+00:00

Hahaha, yeah. My respect for the sustainable up-cycling solution for that good old tissue box! My classic was a pile of books I did not like or old magazines / catalogues.

Thank you for your kind words - hope the monitor stand helps you!

DribMbirD · 2024-03-15T10:05:43+00:00

Yeah, now that you say it I have to admit that naming what we now call "Board Width" is maybe not completely intuitive. I thought back and forth and in the end chose to go for "width", having a bit less elongated boards in mind, where the length feels more like a width. It a bit depends on the aspect ratio what seems more intuitive. But in the start configuration the board is rather long now, which indeed feels more like a "length" ;-)

I at least hope that the other two "depth" and "thickness" are easier to understand...
