I made them in blue with an Ultimaker.
Very cool build! Are these done in PLA plastic? I would be curious to hear about your experience. Cheers!
Yes, they are made of PLA and build by my Ultimaker called Bob ; ) I wrote this blog post about the process and the final result on a danish site for engineers, see: http://ing.dk/blog/3d-printede-hoeretelefoner-del-1-158674http://ing.dk/blog/3d-printede...
It was a lot of fun, but the next pair are going to be better and more carefully made and assembled.
