Hi,
there is a meetup of the Musical Instrument Makers group every Friday at the Fablab Berlin.
Me and a couple of other Berlin Axoloti Users will join there in the Future.
It is a really nice place with a lot of interesting tools like 3d printers, cutting machines etc. Feel free to join us there
This is the FB page of the Musical Instrument Makers Group Berlin
