Metro/Intermetro Basic Parts

This is two basic parts that can be built upon to create things that can attach to Metro/Intermetro racks.

The first is a clip base that wraps around the 1" poles, with an inner ring to catch the notches on the pole. It is 60mm tall, and wraps 250 deg around the pole. Adjusting the height and infill, and material, will determine the strength of the clip.

I have also uploaded a 25mm variant, though I do not believe it clamps tightly enough to be useful. WIP.

The second is a hook whose inner radius matches that of the wire along the outer edge of the rack.

Included here are FreeCAD and STEP files.
