Very minor mesh changes - Slightly deeper grooves, overhangs reduced, attachment pins scaled up slightly. Thicker

You'd barely know by measuring the original with this, but the less support you use the happier you'll be, it's a nightmare removing any supports from the tracks, especially with the PETG I used.

Should print fine with only Buildplate supports. Single pin side down.

Suggested nozzle 0.2-0.4
0.1 to 0.2 layer height.

Cam-Final.stl Is a full rework in Fusion 360 which prints perfectly with minimal buildplate supports.
0.4nozzle, 0.1 layer, 100% fill, PETG
