Replacement Track Support for Marble Run

Functionally identical replacement track support for the Quercetti Skyrail marble run.

So many of our supports had broken that the marble run was practically unusable. I made a v1 that looked like the original but it required support to print.  I recently had to print some more pieces and did a redesign to make a v2 part that does not require support. It prints quickly and only requires around 5g of filament.

The track fits reliably into the clip however I have noticed that sometimes the fit of the support into the holder is a little loose (I guess my printer is not perfect). I include the FreeCAD file in case you need to edit the part to fit a little tighter into the holder.

I print with 0.6 nozzle, but keep the layer height down so as to keep the track fit tight with a satisfying click.
