Havent done a lot on the big Omega in the last few weeks, been a bit time poor. plus waiting for some LEDs and fibre optic cable to arrive for it. Mostly just sanding and puttying of the rotating sction, but hoping to have that primed and read y in a week or 2.
In the meantime i've also resized and printed a fair part of the main superstructure for a smaller 50cm version.
Its not as simple as just resizing 50% and hitting print, as many parts have screw holes that need to be changed, or screw clearances changed. And some parts have detail thats already at the printable limit of small details, so have had to edit a bunch of parts, either thickening or changing some detail. In some cases i'm able to simplify construction by combining some parts, in other cases i have to go from screw assembly to just glue. The blast shields at the front for example are 3 layered, and at this scale work out at 0.75mm, 0.5mm, and 0.75mm, and dont work being screwed together.
The detail panels for the rotating section had very small fine lines, am having to change those a lot.
But its getting there. This is my prototype, so as i print and assemble i'm seeing things that need changing, so the CAD model has updated parts that i havent re-printed yet.
