Bracket for electric motor: RM-500 series, RM510 TRQ brushed motor

This is a bracket I made for an electric motor that is used in model building (in this case a ship). Designed to fit the motor snugly, with multiple holes (M4 size) to attach the bracket.  I have printed it in PLA, however PETG would probably be stronger. 

Printed with solid infill (it needs to be strong) and with some supports for the bigger holes.
