CR-7: extend y moto dock (double side steady)

thingiverse

Double the site makes it even stronger! And if you adjust the end limit setting, you can let the wheel move to the end of the rail. With both sides fixed and the y-direction fixed screw extended, the belt becomes tighter after stretching, making it harder for the motor position to shift! And by changing the limit switch position, you can make the wheel move all the way to its farthest point. Initially, the aluminum extrusion length was 25cm, but now I've managed to extend it up to 19*15.5cm. The design concept was inspired by http://www.thingiverse.com/thing:1099705/, but I redrew it from scratch. I left some space for the limit switch holes so you can move the wheel all the way to the end of the track!
