Built using PLA on a cocoon-create (Wanhao duplicator i3) (200x200 bed) only modification was using a carbon fibre rod as the truss rod - meant it was much lighter.
CocoonCreate Duplicator i3/Wanhao duplicator i3
Tried the neck with a raft and it failed due to overhang - was fine without the raft! Used 8mm carbon fibre tube for the truss rod instead of steel - much much lighter! Couldn't locate the right length socket bolts so used cross-head ones and it works fine. Metric was M4.
Used hobby spray paint (suitable for plastic) and prepped with spray primer/filler sanded down to 600 grit - greatly improved the feel of the fingerboard. Basically this build worked straight off the design - very impressive.
