* Tips: Try to keep the rods parallel and the four acrylic pieces parallel. The Y-axis
must be a rectangle, that is the rods on both side should be parallel, so is the front and
back plate. Otherwise it will cause obstruction for the belt later. You can use a Digital
Caliper to measure.
*Note: As we re-designed the rear plate, there are two more holes on A12, in this
case, you need to use the screw locking ring to fix the smooth rod.
