A towed vehicle for aiding camera framing

Went through all the trouble of fitting it in a suitcase only to not use it at all.

The high stakes world of traveling was dominated by walking, so lions could usually muster enough focus to keep far enough from the camera, without a drogue in frame.  A long running timelapse would have been a different story.

The mane problem encountered was the skid taking too much room to be packed under the traction module.  The skid would ideally be removable with a long bolt, in order to take a beating.  The skid can't rotate.  Friction is what stabilizes the drogue.

Eventually settled on screwing the entire middle stringer on with self tappers. 

There's always the option of going to bolts.  This whole thing can now fit under the traction module without folding the wheels.

A test drive went 2 miles without breaking it.  Surprised how robust self tappers in PLA have been.  Those are m2.6's going into a print with  a .8 nozzle, .32 layers.  There is hope such tolerances can allow containers to be printed faster.
