should the metal axle be a separare part?
2025-10-30 22:10:47
or would it be sufficient if there is just a metal dot at the front?
is the metal axle length correct? if this motor is a standard flat DC motor the axle should be longer (nearly to the back of the housing)
did anyone open one of these? is a "normal" motor inside (like the 12V/4V replacement train motor) or something custom?
is the cone at the rear correct? as of now there is a gap at the assembly where you can see inside and see the axle...

I think it's fine to leave as is. The inside axle will almost never been seen.

this one could still be scaled to
1 16 0 0 0 12.5 0 0 0 0 12.5 0 2 0 4-4cylo.dat
and move the cone to close the gap in the assembly

Do you have the part, or know of any closeups?
2025-11-01 16:21:32
just zoom in on 74569p01.dat at the connection from this to the outer shells, as of now there is a gap where you can see the inside and the inner part of the metal axle...

Yes, I know since I put it there, but how does it look on a real part?
