About this model

I used these to upgrade my Proxxon MF70 to brushless motor. This kit includes a part which is 6MM thic to mount the motor to MF70 body. Another 2 parts are the coupler to connect the motor to the spindle. But it's only the motor-side. Given that the motor speed of a brushless moter is very high and considering the durability of the parts. I made the center part of the coupler with aluminum, while the fans of the coupler was made with 3D printing. Also the motor mounting kit was made with aluminum to help cooling for the motor.
