Finally was in the mood for some PCB work. I'd be lying if I'd say that I don't feel a little bit smug about this v3 mobo
Because it's tiny and fully reversible. I'm particularly smug about that reversible nice!view display connector. Oh, and it scales to 4x6 matrix for larger builds too!

Re: #3dprinting & #3dDesign
I've become ... 'better ' at it, but one of the core things I'm missing is how folks do design when it needs to work with other complex parts.
For example; My #3dprinter is basically a custom component at this point. I had to design the sled to use with the rails, every component outside of the bed-base and the extrusion frame is custom or customized.
I'm looking at making a big upgrade to the hot end but nobody makes my part, and I need a cooling solution. So how do I design a fan/duct system that mounts to my hot end mount, fits all the pieces and is the right length?
It seems incredibly daunting to have to #CAD up the entire assembly from scratch. But other folks do this... Somehow? If I look for cooling solutions on any print-sharing website there are thousands of them.
What am I missing here? 
I've generated many #hdri environments maps and soon I will release all for free, are simple and maybe useful for product visualization and check of surfaces. #b3d #Rendering #CAD
I'm a big fan of TinkerCAD
( tinkercad.com ), it's a great entry-level #CAD tool with an excellent interface (which is much more user-friendly than most professional CAD software). But the new Skatcch tool they recently introduced takes it up a level and allows for almost real paramertic design.

OpenSCAD 2021.01 now availabe on Haiku (64bit only for now).
Thanks to @joe for pointing this out and the pointer on building it for Haiku!
Thanks to @waddlesplash for poking me into looking to porting it to Haiku! :)
EDIT: after fixing CGAL for 32bit, OpenSCAD is now also available for that on Haiku.
Enjoy!
A bit of #FreeCADFriday action: reworking the sleeve for @MCQN_Ltd's RGB LED bollards so we can (a) switch the 3D printing orientation so the stress lines aren't along the printing layers and (b) it will be removable for when we want to mount the bollard on the back of a trike for another music video (or something)
#FreeCADfriday I am almost done with this "simple parametric t-maze" for laser cutter. The challenge here was to use the variable set VarSet with a drop-down list (App::PropertyEnumerate) and to use IF statements in variables.
The project is available on Github here: https://github.com/mathiaslec/simple_parametric_t-maze

I enjoy model airplanes, but I’ve always found it curious why #CAD software companies always seem to use model airplane engines as their models for their marketing?
Maybe I’m wrong, but it seems like most RC airplanes are electric these days.
Weirdly, the engine model seems both overly complex (from a geometry perspective) and overly simplistic (not as many parts as most people work with in actual assemblies).
Do many people today even know that it’s a model airplane engine?
Finally starting to get the hang of Fusion 360. Designed one part, modified a second one and succesfully joined them. Printing now.
Apart from the permanent frustration caused by me not knowing how to CAD, I actually like working with Fusion. I will give FreeCAD a chance but I'm tempted to figure out how to run Fusion on Linux in my ongoing fuck Windows migration process. Might be easier than the VR sound problem...
#CAD #3Dprinting
After extensive testing, here’s a 3D model of a Velcro-equipped speaker casing. Designed for a design session where users can explore different placements on a wearable element. As always, modeled with FreeCAD. #3DModeling #WearableTech #SpeakerDesign #FreeCAD #ProductDesign #Prototyping #TechInnovation #IndustrialDesign #OpenSource #HardwareDesign #Engineering #DesignThinking #CAD #Makers #DIY #Acoustics #ElectronicsEnclosure #FLOSS #design #uidesign #tui #wearable
“If you've ever maintained the same piece of software for more than a couple years, you'll understand how hard it is to pivot already-finished #tools to learn from #ParadigmShifts in the industry. Even if you try your hardest, it's very easy for the old way of doing things to be woven throughout your #codebase as assumptions.
As #JessFrazlle mentioned in her first post, this is why most #CAD software is not extensible. Most of them have assumptions about software that were true in 1990 but aren't anymore: that the #internet doesn't exist; that #GPUs don't exist; that clicking is easier than typing for most user interactions”
#software / #engineering / #API <https://zoo.dev/blog/api-first-approach>
Ok, so I've realized belatedly that #onshape #cad does in fact support functional abstractions of parts over dimensions, which is neat.
You just gotta make a part, go into the "configurations" panel, "create a configuration variable", use that variable in your part, then in another part studio you can do a Derived feature referring to the first part, and then you get to specify a value for the "configuration variable", i.e. pass argument to the function.
I got tired of all of the cables kicking around the junk drawer so I designed and 3D printed a bin to hold them.
