s0lstice requested that the next time HydraRaptor was extruding into fresh air I should post a video, so here is a video of a part with a large covered void being made: -
Spanning a void from Nop Head on Vimeo.
It is a bracket to mount a tiny stepper onto a Darwin corner bracket.
As you can see, the unsupported layer is very untidy, but the next layer sorts itself out. The reason I had to make this side the top is that there are projections on the bottom to mate with the corner bracket: -
Here is what it looks like installed. I need to sort out a shaft coupling. I have no idea if the motors will be powerful enough though.
I also made some feet for my Darwin to stop it scratching the table: -
I stuck felt pads, that I happened to have, on them, but rubber would probably be better for non slip.
