Looking for measure of this motor I've found that they vary quite a bit from a manufacturer from the other, despite having the same 380 or 385 name.
Specifically, some have the holes in the front tilted by 15° or 16.5° from the back leads, the front bushing housing seems to be either 2.5mm or 3mm and the back is either plastic or metal, case length is given as either 37.5 or 38, diameter is sometimes given as 28, and of course there are various shaft lengths. I believe most of these measure differences are from rounding (except tilted holes) but maybe there are many variants of this.
The model is same as the one in the attached schematic except that it has a third hole on the front, which I located best as I could.
L1 is 16, L is 57.
Tried to put in the vent holes too, they're somewhat accurate but check your model for differences.
Mounting screws are M2.5 as indicated in the schematic.
Included STEP file for easy import into other documents.
