But i re-measured, and it seems that the model has small error too.

From the model: inner length = 127.34079 measured from print 127.2
phone 127.75

inner width = 65.443081 measured from print 65.3
phone 65.0

I just ordered some Premium PLA 90 from Orbi-tech. Lets see is it any better, color selection is poor for 1.75mm (3mm better)

I think i have asked, but what cad do you use? possible to share originals under DWTFYWT-license ? or just for me, i'll buy you a beer or ES
Yes, there's is a small error in model but not so big as that comment in GitHub indicates. I measured the dimensions with a simple ruler and made some scaling afterwards so there's definetely small errors (+-0.5mm) + PLA shrinks a little.

I modeled the model originally with Autodesk 123D Design: https://www.123dapp.com/design
The .iges and .step can be found from here: http://relativity.fi/jolla_toh/3dmodels/ (I'll add the DWTFYWT-license). Those were converted with FreeCAD from .stl back to solid models. I can of course provide the 123D Design file too if needed.

oooh there is mi problem.
The triangular STL is almost impossible to edit... this has now been gone to the STEP file too... I'm just heating my printer up.

EDIT: Previous stl was crap. this should be better.

Print finished.
Have to move the power switch opening a little, and add a smal notch to the bottom edge

Attached is the tuned STL of OH outer frame.
Just add your own stuf on top of it...

I looked at the frame with Netfabb Basic, and it marked the part as 'damaged'.
It seems something weird about the four corners...

Very interesting project.

I'd like to add serial port (UART RX/TX pins at least) capability to Jolla with I2C.

Are there I2C to UART converters that could do this ?

--> either SC16IS750. Has 3.3V operation, but you'll need I2C levelconverter (e.g. PCA9517) and 1.8V regulator. Easier to interface to the 232 transceiver.

--> or SC16IS850L. Has 1.8V operation, no need for I2C level converter, but needs 1.8V regulator. and some tricks to interface to 232 transceiver.
