Spacecraft IDSS Centerline Docking Target (reworked)

I adjusted the backplane piece of @maxfagin_179712's model to better match the specifications on the backplate polygon markings and the 5 reflecting elements.

You still need to go download the alignment-cross.3mf and connecting-rod.3mf on the original model page!

I printed this at 35% (to fit 180x180mm) on my Bambu Lab A1 mini with ironing to get a nice finish on these large horizontal areas. The file I used is attached and includes further adjustments:

• wider lines for better printability at this lower scale
• local modification of the infill direction & density as well as top surface infill pattern
• closed out the hole for the screw on the target piece (because I intended to use glue)
