I've got a C920 webcam, it is mounted on top of a monitor, but it overlaps with the actual screen a bit. I've looked around and found out that people just 3D-print spacers [1]. I never 3D-printed anything. I assume I'd have to adjust the spacer dimensions to my monitor.

What app I should use to edit and STL file, as a beginner? Where do I get this printed, preferably in Brno?

@oleksandr not sure if there's anything better for editing stl files, but i do it in openscad -- mainly because i don't know how to use any other tools.

the prusa slicer (and perhaps other slicing tools) can do some rudimentary editing too.

also, i'm happy to print the model for you if you send me the stl file. also, if you show up in the #base48 hackerspace i can show you how to do so.

@oleksandr also, i think some people were running 3d printers in the red hat office. i don't know the details, but you may be able to dig some pointers from the brno-memo-list@ archives

@lkundrak OK, as the first step I'll measure the bezels and then try to play with the STL file. As for RH, I found the info in the mailing list, but it's not really work-related, so not sure if I should bother people.

@oleksandr as far as this model goes; publishing just the .stl file instead of the actual model is a little dick thing to do. essentially an equivalent of an .exe file with no source.
but looking at the model -- pretty sure modifying this is more work than designing from scratch. this literally takes 5 minutes of openscad with no prior experience.

@oleksandr i don't think any 3d printing is work related, considering the nature of red hat's business. pretty sure this is not intended for work related stuff

@oleksandr not really a direct answer, but I've got a C925e and it has one of those standard tripod threads on the mount. So I just stuck a small tripod head adapter to the back of my monitor with double-sided tape.

@lkundrak Hopefully. I did only simple templates in LibreCAD, and I do not remember anything from my university experience with AutoCAD.

@oleksandr @lkundrak this design looks so trivial it will be faster to just draw it from scratch in FreeCAD. It's just an extruded polygon with some rounded edges that aren't even really needed.

I can draw it for you in 10 minutes if you get all the dimensions

@piggo @oleksandr i'm fairly certain you're right.
spend a week learning freecad and then draw it in 10 minutes :)

@oleksandr i suspect you could transfer some knowledge from other cad systems to freecad, perhaps, but openscad is a procedural cad.
you write a program that generates the model. it's closer to writing C or perhaps postscript. you got primitives that generate essential shapes (cubes, cylinders, spheres), operations atop them (translate, rotate, union, difference, intersection) and structured programming constructs -- subroutines, loops, variables and conditionals.

@palmer as long as you have space behind you monitor, you are good, yes :). I've researched for some tripod mounts that can be clamped onto my MSA20 monitor arm, but it's not that trivial.

@lkundrak @piggo I assume that round edge is needed because it grabs gently onto the very outer bezel, which slightly tips over the actual screen plane

@lkundrak sounds like TeX

@oleksandr ya, makes sense -- I've got ton of other stuff stuck to the back, so I guess I forgot some people don't...

For the actual 3D printing stuff, I just use TinkerCAD. That's about as much CAD as I actually need ;)

@piggo @oleksandr here's how i do these rounded things in openscad; just place small spheres in corners and do a hull() around them (imagine wrapping them in a plastic foil)

@lkundrak @oleksandr i think that grows the dimensions by the radius tho?

also with more complex shapes it gets really badly slow. especially when using the other method whose name I forgot.

rounded things is really what made me switch to freecad, it's so much less hassle

@piggo @oleksandr yes; the spheres are centered on 0,0,0, which is why i translate them by the radius.
and yes, it gets slow. i sometimes draft with $fn=10 and then raise it upon doing the final render.
i'm not competent to comment on the rest, because i'm not smart enough to understand freecad.

@lkundrak @oleksandr the only thing to understand is to get a feel for when it will crash, and never brush it the wrong way. the learning curve is really bad

you get the hang of it after a couple weeks or so

@lkundrak @oleksandr though it crashes a lot less frequently with the recent updates

@piggo @oleksandr i recently figured that openscad hangs if i do an infinite loop, which is pretty hilarious
(other than that, it's not at all too crashy)

@lkundrak @piggo something like this?

@oleksandr @piggo looks okay to me. (and i'm not sure you need round edges anyway -- this is probably going to be just fine when printed)

@oleksandr hey @piggo look ^^^ dude become an #openscad pro while freecad was still starting up!

@piggo @lkundrak I'd probably want to print it then. Not sure if all the dimensions are 100% correct, but I did my best :). I can come to Base48 indeed if you are so kind to meet me there and guide through the process.

@piggo @lkundrak TBH, I poked TinkerCAD first, and it looked oversimplified to me. Then I poked FreeCAD and instantly remembered why I used LibreCAD for 2D modelling instead. Then I poked OpenSCAD and thought something like "well, this is the lesser evil"

@oleksandr @piggo tell me when. there's a grill party every friday (like, right now), but i'm happy to stop by over the weekend too. i just need a few hours of advance notice

@piggo @lkundrak you mean, I can come even now?

@oleksandr @piggo yes. if you want to meet there, make it 20:00 near the no. 82 door (next to the amici pizza) https://en.mapy.cz/s/gecovubuso

@piggo @lkundrak ok, will be there!

@lkundrak @piggo it's black on black, but it actually fits and works!

@lkundrak @piggo should be visible better

@oleksandr @piggo yeah, pretty cool.
translucent pink next time.

@piggo @lkundrak …with a LED strip around and some pills against epilepsy glued…

@oleksandr @lkundrak @piggo this is an amazing thread about 3d printing and maker in general success story, from the first inquiry from someone unfamiliar with all of this to a finished working thing in 5 hours!

@vbabka @oleksandr @piggo a heartwarming story about an engineer who could install a web cam ❤️

@lkundrak @vbabka @piggo 💪💪💪

@lkundrak @vbabka @oleksandr @piggo If you were Apple, you'd leave the webcam covering the screen and call it the Dynamic Black Place, and people would give you billions for it.

Anyway, welcome to the world of 3D printing and modeling. Warning, it's addictive...

@kbob @lkundrak @vbabka @piggo I wouldn't mind covering a bit of the screen, but I've got Konsole tabs there
