Original Grey Technic motor from 1977: 6216a

[Jens Bauer]

I made 3 primitives for axles:
Axle Endcap
Axle Endcap with Hole
Axle Groove (now renamed)

(Max kindly pointed out to me that the quads on the ends are warped; this was not intended and I'll attempt to correct this for next submission).

The end-cap for the motor has been updated too.

I submitted updates for the two axles, which use the above 3 files:

Electric Technic Motor Plastic Axle (1982 variant)
Electric Technic Motor Plastic Axle (1977-1979 variant - also use by gearbox)

At some point, I expect to 'close' the unseen end of both plastic axles.
(Sorry for the many extra re-submissions; I wanted to make this submission of as good quality as I could).
