I have made a 3d printable mount for the N5065 motor that works with the AMT102-V encoder which can be found here.
This model was made so that I could also include a duct and fan to aid with cooling of the motor.
However I found that when I printed and tested this concept the fan did not aid much in cooling. I have ordered a more powerful server fan which will hopefully make a bigger difference. When I get around to testing that fan I will post the results in a separate thread. In the mean time I thought others might find this model useful for getting started with this motor and encoder.
Edit: I forgot to mention (it was on grabcad though) that only the motor mount and duct are my own. The model of the N5065 motor is by Paul Guenette (@Wetmelon below), the AMT102-V Encoder is by Electropioneer Serbia (AMT102-V Encoder) and the DC fan is a modified version of the model provided by Andrew Thomas (60mm DC Fan)
