wallace.scad assembly view doesn't show all the pieces

[triffid]

eg you only have one base_end, one leadscrew_coupler and one z_top_clamp.

also could I suggest adding shadows of the motors?

I'm planning an update that will require modifying most of the code in that section. Adding the duplicate parts probably would have happened anyway, but I'll keep the thing about the motors in mind as well.
