Hi Kunstmaan.
If you go for the shown design I think it should be in one piece. Collar and Sun1 in same 3D print.
The missing axel to hold the planet carrier 1 , most be modelled as a part of the Sun1 gear and the motor axel must be covered totally.
The motor have no support !! What happens when you tighten the nuts??
An alternative method is to bore a hole through the Sun 1 and the motor axel for a 2mm slotted spring pin.
I will advice you to by gear wheels at the former mentioned company, I have tried to 3D print the Sun1 wheel, with a bad result,
it can maybe be made if you can made layer at 0.05 mm.

A gear as Sun1 (G0.5-24) is not avilable wiht a 8mm bore.
I havent found pinions on there site, but maybe I not been in the correct place on there site

OK your right thats a workshop problem.
My husband tried to 3D print the gears what resulted in a failure as said before
So what steps must I make to enlage all the gears from mod.5 to mod.8 just to create a working 3D model. For that project I have a 36GP BLDC3650 motor

Hi Kunstmaan,
Before take so much time of Oldbelt helps, please check you 3D Printer abilities and make an example of what is the gear tooth most little that the machine are able to do so from this base make an option for the all new planetary gear.

Hi GIOV,
Youre correct, but witch commercial party could I use??
And what would be the best material to use

Hi Kunstmann
1.-I think you need a good mechanical properties for the durability of you planetary gear that will run so fast. I recommend to you go to one specialized place for print you assemble with Poly Ether Etherketone (Peek). I know about a Funmat 3D printer or Cincinnati SAAM HT High-Temp Automated 3D Printer, able to do this.
2.-For do the correction of the planetary designed by Oldbelt, You need apply the following Feature in AD: Scale or Mirror (In this case Scale) and make the scale of your assemble in base of the better Gear Tooth size that the machine are able to achieve. The most important is keeping the relation between all planetary gear components in base the Sun1 to achieve the same RPM that you need.
