Mike, I know you said you were busy until late April, but can you come in
and present Freecad and your vision for Freecad for an hour at Replicator
Wednesday this week (03/28/2012)? I'm really interested in the project and
I think I can get some others in the community interested in checking it
We can have a few presentations using the big screen and audio. I'll ask
Matt to come and show off his http://reconstructme.net/ kinect based
scanner, and I'll present some things I made with the elegant and simple
Of course Andrew Rutter will also bring in Type A Machines prototypes and
have them printing samples.
Replicator wednesday isn't just for the 3D printer types, in lieu of any
other regular meetings we are the de facto regularly meeting fab group at
Noisebridge, focusing on all the things to make all the things. If you
want an introduction to the Noisebridge tools shop, the Makerbots or
Repraps at Noisebridge,or the Nb Laser cutter, come to Replicator Wednesday
the first of the month (04/04/2012 in April) and we'll give everyone an
