I remember this fellow when he posted his self- made CNC build on one of the RC forums several years ago. It caused quite a stir among the XYZ nerds :) I believe he then did a limited kit run & now possibly turned that into a side business by the looks of it

Anyway I stumbled on him again in YouTube land. Looks like he has been busy on other interesting projects. In particular, some of you guys have been talking about metal casting off 3DP parts. Check out THE HAMMER. Its more classic casting vs. the lost-wax-like (burn out) method but very interesting use of integrating 3DP parts into a (spoiler alert) cast within a cast part.
