What exactly do you want to print? At the position of the flange nothing has to be printed, only at the gearbox output. And for that different CADs are available in the forum, depending on how the rear part of the propulsion unit is designed, different solutions exist. Just search for “Reisenauer”.
Just like I wrote. I want to 3D print the chief and the flange at scale 1:1 and no, there are no Reisenauer CAD on this forum - that I am aware of (I have been on the forum from day 1 but I may have missed a thread ) nor on the Reisenauer site…
Now I understand what you want. At Reisenauer’s page it says the PDF for the Motor Chief will be added soon, so you could ask them about it.
“Federal” is a translation error, it says “Bund” in German, but as I also don’t know what this is referring to on the gearbox, I can’t give an exact translation either. But I think “collar” goes in the right direction. It is definitely something round.
Federal in the first diameter before the bolts , the hole you have to drill in order to hold the gearbox after the propeller by the 3 screws
It refers to the "motor holder " section
1 length and radius of shaft fitting (or whatever it is called)
2 radius of the first metal “cylinder” (is that 19.5 mm ?)
3 radius to the bolt center (15 mm, right Alexandre) ?
4 first metal cylinder thickness
5 Square metal thickness
6 second cylinder thickness
7 base cylinder thickness
8 Bolt radius -M4 -> 2 mm
