Egg Beater Handles for old style Swift-Whip ball-drive eggbeater

Egg Beater Handles for old style Swift-Whip ball drive eggbeater (made in Australia).
Fully parameterised design.
There are two parts: The "Top Handle" and the "Crank Handle knob"

The metal of the egg beater will outlast even the "War on Terror", but the wooden and plastic handles break after a century or two. My grandfather used this very one to beat his kids during the great war.

These replacement handles are split so they can be retro-fitted to the riveted rods.
File contains a useful function to make spherical section cylinders.
