What are your favorite resources to recommend for beginners?
I’m wanting to get interested for doing a cyberdeck case, and/or custom cluster racks for Raspberry Pi’s but any and all newbie resources would be appropriate for this question.

At some point you’re going to need to recalibrate your printer. The prints just won’t be as good as they should. And it can be very very frustrating trying to figure out what’s wrong. I highly recommend this website: https://teachingtechyt.github.io/calibration.html
Excellent! Not something I would’ve immediately thought of but sounds critical to good prints.
Teaching tech is good
I’d also add troubleshooting guides from all3dpI would suggest, however, at least checking calibration even if you’re not changing anything- and inspecting it out of the box. (Are the axis square to each other? Is the bed loose? Is the frame? Belts tight but not too tight?) if it’s a lower end… yeah? There’s probably something that needs tightening.
If it’s a higher end printer, well it’ll give you an idea of how it’s supposed to be.
Other resources…
As well as Prusa, this guide in particular, but the community is very helpful.
Also, I’d suggest staying away from thingiverse. A lot of the models are ripped from non-free sourced (like cults3d or my mini factory.); and many of the stls there suck anyhow. Printables my go to.
For more esoteric content… I’d recommend CNC Kitchen there’s always good stuff in their videos, even if it might not be “basic”
Finally… don’t freak out. There’s going to be a learning curve. It’s okay. Take it one print at a time, accept that spaghetti monsters will happen. (Just tell people it’s abstract art,)
For calibrating printers, I would recommend Ellis’ guide: https://ellis3dp.com/Print-Tuning-Guide/ It covers how to calibrate your printer with popular firmware options (Marlin, Klipper and Reprapfirmware)
For CAD, a free and open source option I have used is OpenSCAD, it’s CAD with code! If this isn’t your sort of thing, you could try OnShape - it’s free with some limitations
Oh actually I never realized that about OpenSCAD. That’s sick!
If you want to try using Blender I recommend this video to check out if that’s the road you want to go:
Learn Blender for 3D Printing - Complete Quick and Easy Guide (Beginner)
Depending on your experience you might check out existing models on sites like printables.com or thingiverse.com
While not for 3D printing specifically, Andrew Price’s donut tutorial on YouTube is a great primer for learning to use Blender and all is basic functions.
I actually have used Blender pretty extensively, I was on the Blender forums way back.
I didn’t realize I’d be able to use Blender for the modelling because I assumed the sizing would have to be fairly precise.
You can definitely make accurate models. Its a little more unforgiving than CAD if you need to go back and fix something, but you can definitely make precise models for functional prints if you do it right (such as inputting specific measurements when doing extrusions, etc).
The Free and Open Source Software options are FreeCAD and Blender. These are not trying to manipulate you in any way. You 100% own them, your products from them, and this can never be taken away from you.
I use FreeCAD for all of my designs. All CAD software has a substantial learning curve. There are 3 common modes of design. You can make parts: programmatically with OpenSCAD, like wooden building blocks/Lego’s, or using 2d sketches and performing 3d operations like extruding and pocketing. FreeCAD can do all 3. Check the official documentation to get started, it is very high quality. The workbenches can be a bit confusing at first. If you want to do the building blocks style, learn to use the Part Workbench. If you want to do sketch based design, use the Part Design workbench. Don’t worry about anything on any other workbenches, they are for advanced operations you do not need.
I use FreeCAD for most of my stuff now, but I found it very, very hard until I watched some video tutorials. After a little training, I’m really happy with it. I tried OpenSCAD, and that can be a really good option depending on your background.
You will also need to choose a slicer, or try some different ones. A lot of people like the prusa slicer, but I’ve never tried it. I started with the cura slicer, and it worked well enough that I haven’t tried anything else. It seems that some people really like the new orca slicer, so that might be a good choice too.
If you can connect a computer to your printer (either raspi, or something else), some software to manage that is definitely helpful. Octoprint is the most popular option, and maybe the only one; so look that up if it’s something you think would be relevant for you. There is also something called Klipper for upgrading your printer’s firmware. Whether or not that’s for a “beginner” depends very much on what their background is, but it’s something to consider if the additional features sound worthwhile.
I don’t know if these are really the kinds of resource suggestions you had in mind though.
Any specific video suggestions for learning FreeCAD?
This is the one I started with; the ui has changed a little since then, but the basic info is still good I think. https://www.youtube.com/watch?v=NXN7TOg3kj4
While not open source, Fusion 360 has a free for personal use version if you are wanting a fairly easy to use CAD program. I had been using mostly Blender up until recently since learning how to use Fusion. I love being able to parameterize everything. Blender is awesome though in it’s own right. I use both for making functional prints depending on what I’m trying to do. I tried FreeCAD, but it definitely has a bit more learning curve than Fusion.

I’ve used Blender, Fusion360, and Google Sketch. So I’m somewhat familiar with 3d modelling. I guess I was thinking more along the lines of Hardware but Software compatibility is a good topic to cover as well.

Honestly I don’t know what I don’t know. I assume there are hardware items to learn about.
I’d say printer recommendations, specifically how to pick one, where to buy from, should I build it myself?
I’ll check out the Prusa book because I’d assume beginner material probably also covers this. However I’ve seen online community recommendations differ from authors quite a bit (saying Generally for hobbies).
