The model is not modelled for 3D printing...!! But it prints fine...
The 'nose bridge' [?!] is made fatter and some parts are 'booleaned'.
Printed on Ultimaker...!
Update: the files glass are more or less in the right scale [the 'glasses' files are really big]
Update: Added also the 'complete' glasses. For dual color print frame and electronics separate. For monotone the 'complete' glasses will do...
