Martin Pearson has been busy again and produced a really useful Servo Mount. The gcode file produces a single print of three pieces which need to be separated and slightly cleaned before assembly.
Holding a standard SG90 servo a piece of stiff wire is attached to the servo arm and passes through the vertical slot of the slider. The clip on lid provides a method of attaching micro switches which can provide feedback on the position of the slider at both ends of its travel.
Keith found that he had to glue a small shim to the contact surfaces to make sure the switch activated.
This might be down to the type of micro switch being used. I used one with an actuating arm and the range of movement available in the mounting slots was ideal without any modification.
A partially assembled example is shown below.
The base has two mounting holes for securing to the baseboard and the slider can be installed with the actuator bar facing left ( as in the picture) or right.
The three pieces click together without any glue. Very clever design Martin and thanks for sharing.

I used the micro switches from the MERG kit locker as I already had them
ReplyDeleteMartin printed me 17 mounts and all work very well, I also used the PCB version of PMP 18 Ezypoints to control the servo
