Nice work, the board looks good.
There are a lot of free CAD programs out there, it'll take longer to master them then the printer.
Good Luck!

Thanks so much. That is my first board and learning Kicad wasn't easy and I'm amazed I actually got it all together & working.

Yeah, I'm overwhelmed by it all already. But I gotta take a shot at it.
Any recommendations on "best" FREE CAD software?
Update: Right after posting I saw your #3D Printing article. Reading it now.

AutoDesk offers a web based CAD tool. I've used it with my 3D printer. It's free for a moderately crippled version.
The difficult we do right away...
...the impossible takes slightly longer.

No, I've used TurboCAD for years and it's not free.
I'm getting better at doing CAD but still have trouble here and there.

I really like OpenSCAD - CAD for programmers. I've been able to make some pretty cool designs without a lot of difficulty.

Fusion360 is free for hobbyists and great for 3D printing. Lots of great tutorials on the web and a very active community. HUGE learning curve for sure. Downside of the free version is printing full size plans on actual paper. Not a prob for 3D printing, but is if you are making stuff out of balsa.
Tinkercad is great for really simple stuff. Super easy to learn, but you'll outgrow it quickly, better to invest the time in learning Fusion360.
Blender is really good for sculpting and "natural" shapes. Also a steep learning curve, but easier than Fusion360. More for artists than engineers maybe?

Have a look here: Adventures in 3D printing Part 1: Fusion, you CAD![^]
Adventures in 3D Printing Part 2: Rise of the 3D Models[^]
Adventures in 3D Printing Part 3: Making Complex Apertures - Recovering from the Bends[^]
And very important things:
1) Getting the bed levelling right is really important. If it's "low" on one side then that side will print too loose and then it'll detach and melt itself to the hot end. And it's a PITA to clear it off because the head needs to be 180C or so to melt the filament it's covered in so you can't touch it (especially not with a wet cloth!)
2) After bed levelling, the next critical thing is the bed and nozzle temperatures. Check the filament manufacturers recommendations and start right in the middle of those.
3) Material. PLA is easy to work with, but not very strong, and it's glass temperature is pretty low - so it'll sag if you leave it in a car in the sun! It's also not as durable as PETG, which is about as easy to work with, though it needs a higher print temperature. ABS beats them all in everything except actual printing - I abandoned ABS because PETG gives be much more reliable printing. My hot end still has traces of ABS from the last "birds nest" it created ...
Have a look here as well: PLA vs PETG: Which Material Should You Choose? - 3Dnatives[^]
Good luck - and persevere! It's surprising just how many things you didn't know you needed to make that can be printed. For example, I'm making kitchen cupboard doors - so I've printed three jigs for the handle locating holes: they are all in the same relative position and I don't need to measure anything.

Thanks so much for taking your time to give me those tips.
I will definitely check out the resources you gave.
As I was purchasing I saw all kinds of stuff about Bed Leveling but had no idea why it is really that important. These few sentences you gave me helped me more than a lot of other stuff I've read elsewhere. Didn't know about nozzle temp importance either. really great stuff.
Thanks again.

Have you tried TPU? We're using it for some bearing covers for work and like the flexibility of it.

I haven't - I know my printer can handle it* but I don't need flexible printing at the moment.

All good advice here. Nothing else to expect from Griff.
I would recommend PLA more than PETG that the site suggests. PLA is considered more of a "beginner" filament vs PETG because it is easy to work with etc... but some of the objections and advantages I think are subtle and a bit over done.
PLA is considered more biodegradable for example, but people that have buried things in their gardens for a few years see that the PLA items are still about as robust as the PETG ones. The other differences don't show much contrast between the filament types (ie. on a scale of 1 to 10, a 9.1 and a 9.2). And I disagree completely with the temperature ranges provided. In my experience, PLA prints in the range of 180 to about 250 degrees, PETG 200 to about 260. PETG is much worse at stringing and self-adhesion between layers. Any models with a lot of "action" are much harder with PETG. PETG has more print failures.
And colour? Surprisingly I've seen more differences between filament colours (and brand names) than between material type.
I have come to the point of printing a temperature tower for each new box of filament, storing it in the box it came in and picking the right print temperature based on what my print model looks like. Something with overhang, sharp edges or flat surfaces would be printed in PLA, something requiring durability or strength would be PETG. Some vendors have something called PLA+ that I am happy with. No idea what it is.
I started with PLA, then shifted to PETG later and have built up a considerable library of (mostly) PETG filament. I have become a bit jaded with PETG and am shifting back to PLA.
Oh and ... Cheap filament is usually no bargain.

Thanks for asking.
It is a very simple device really. It tracks room temperatures and allows you to log them to the SD Card. It also allows you to read the temperature from any room where the device is via Bluetooth on your phone (I have a prototype android app also -- and later there will be iphone). It also allows you to retrieve the data on that is written to the SD card over bluetooth so you can view graphs of the data and see spikes (or dips) in room temperature very easily.
It's just a temperature tracker on steroids.

Excellent. Just look for some 3D Model that is 'boxy' enough to fit your boards and then modify it so that it can actually be used as a case.
My current favorite as a case for the Zwölf would be this thing: Galileo shuttle by 3dmax - Thingiverse[^]
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

Thanks for the tip and the link. That's a great idea. Start with something close and alter it.
