Now that the internals are (almost) done, I'd like to make a nice case for this puppy. To the 3DPrinterMobile!
Now, this looks good and all, but as I forgot to bring my calipers, I had to measure everything with a ruler! Even with the wide tolerances I took, the openings will probably be off by a few mm... Eh. Let's get that printed!
Got lucky here! The board fits perfectly, It's correctly sandwiched between the two halves. The USB port for the Arduino Mini doesn't line up exactly with the opening, neither does the port for the thermometer. I had to slightly trim them.
I think I'll probably leave this project as it is now... The only improvements now will only be software-side: implement the rotary encoder, other sensors, ...
