This is good mounting for the green Maxon motor. The box extrusion was drilled to except the mounting holes and the body of the motor. This fixture did take a lot of skill to make. This is a very stiff mounting fixture. Notice the flexible coupling made of the tygon tubing and the clamp collar.
Flexible coupling are very important when attaching things to motor shafts.
This is a very good sliding mechanism. The delin rollers are much better then just having two flat surfaces slide past each other. This design will support much higher radial load on the sliding part before it binds. Here a piece of Delrin was turned to make a worm gear. This was a very time consuming process.
