Motor Mount for Square Stock

This will fit the home depot chrome towel bars and 5/8" wood square stock. The opening is 16mm. The mounting holes are for bell type motors with three screws (that's a DT850 in the picture) but I plan to upload a version for standard four screw motors. It's designed so that the wires can go inside the tube without having to wrap around the end and be exposed to crashes. I have flown with these more than a dozen times in the last year and they perform great.
