Recently one of the magnet holders for my window shutters broke, and I thought I'd take a crack at designing a replacement to 3D Print. I'd never designed anything in CAD software before, so I had no real reference.
I found FreeCAD extremely easy to use and intuitive. I watched a couple videos and followed-along with the tutorials, then started on my own item. It's a relatively simple 3-part component. I took measurements with digital calipers, and in a few hours was printing the first prototype.
A couple prototypes later (small measurement adjustments to account for plastic shrinkage, etc), I had the final model. Replaced all of the magnet holders since they were sure to go soon, too.
I had fun, and finally used my 3D printer for something "real". Pretty cool.
That is the spirit! A friend recommended me to buy a Bambu P2S: there are parts I want to print and I don't want to model then send them to have them printed, nor to bother my friend all the time. Funnily enough I've got magnets falling too: for an alarm system on the doors/windows and they don't hold well anymore after the years. Then my car's radar detection device (fully legal) doesn't fit nicely in the phone holder I use to that effect: I want it a specific angle (I want it both inclined and facing towards me a bit). So I'll model those and just print them. There are a few things like that where I keep thinking: "If I had a 3D printer, I'd just print a part".
Most importantly: I've got a 11 y/o and I think it's cool for the kid to see how it works.
Already watch a few vids. Doesn't look too hard for simple things.
I post this in every FreeCAD thread: If you're going to start designing something with it, use the spreadsheet tool to make everything parametric. You'll save yourself a ton of time as your designs get more complicated.
Maybe this isn't anything new to experience CAD users. I don't know if other CAD tools do this as I started using FreeCAD after playing with 3D printing.
It's very common (Fusion calls it User Parameters, etc.) and indeed nice practice. FreeCAD has a few ways to do it, Spreadsheets but also free-form properties on objects. It's very flexible in this regard.
The only issue I have with the Spreadsheet is that I need to add an alias for every value I want to use in the Sketch or Part Design workbench. In practice, this usually looks like
A B
width 2mm
length 3mm
and for every cell in B I add an alias with the same value as in column A. Is there a way around that?
The Fusion implementation is awful - you can adjust one variable, one time, then you have to reopen the dialog to do another. At least for me it's always become non-responsive after a single edit, for years now. I've always assumed I'm just holding it wrong, but I don't know. I've moved on.
Slightly unrelated to this story, but I’m curious if anyone has good resources for learning FreeCAD. I have quite a lot of experience with SolidWorks, AutoCAD, OnShape, and similar software, but FreeCAD has always been hard for me to pick up.
Oh wow - over on Reddit, someone mentioned that the Deltahedra YouTuber has started using his own voice, rather than a generated one - and - well, his content is now far more watchable than it was previously!
YouTube was very effective for me to learn FreeCAD. I just searched for some FreeCAD tutorials and followed-along. I had zero prior CAD experience though, so I was a "blank slate" in a way.
DeltaHedra, another great YouTube channel, also released a good video that shows the previous and this version next to each other: https://www.youtube.com/watch?v=bYdobpjTypg
Thumbs up for both of them, but I must say that DeltaHedra has become my new favourite FreeCAD content creator. Especially after he started using his own voice. His old content was good, but his current his magnifique! The quality of the content he pushes is above and beyond.
I was not expecting so many improvements in this version alone, I'm impressed. I was already using it for 3d printing but now it seems it's getting actually good, makes me wonder how I was able to use the previous version.
I am also impressed by how much they are improving things. It just sucks that they are stuck with the OpenCasacade kernel so making stability improvements are hard to make in areas like fillets and others.
I don't follow Open CASCADE very closely, but it looks like they're on the verge of a new major release (v8.0) themselves that looks like a lot of refactoring and cleanup.
I don't know hat version FreeCAD is actually bundling, but from GitHub it looks like a fork of 7.8.1?

Wasn't just printing other people's designs.
Great feeling to measure and design something then have it fit perfectly.

I think that's much easier as you don't have to go back and forth with a spreadsheet.
EasyAlias macro maybe?
