8-sided micro "bellcrank" control horn

This 3D-printed part is basically an 8-sided bellcrank.  (Its NOT a servo horn) This is made for use with SMALL models.  MANY possible uses! They can even be mounted like gears, to actuate bomb-bay doors for example.  Custom-Designed by Derek Micko at Fun Scale Models and manufactured by Rabid Models.

Dimensions:  One inch in diameter, 1/16" thick.  The holes in the arms are for 0.032 wire (1/32" or 0.8mm). The hole in the center is 1/16" (1.6mm).  Weight: about 0.5gm each. White PETG plastic.

There are THREE varieties (so far).  They vary in how the center mounting hole is designed.  One is flat in the center- and one has a 3mm "axle flange" on both sides - and one has a 4mm "axle flange" on one side. The purpose of the axle is to provide extra support to reduce "wiggle" and also provides clearance when using pushrods. Please see the pictures!  This drawing is for the flat version.

This closeup shows the single "axle flange" on the left, and the double one on the right.  The single one is 4mm tall and the double ones are 3mm tall on each side.
