Holder for PWB600 Fixation Stick Simple

Having the simple stick in use I was thinking how to store them and found that there is some room underneath the PWB600, very the origin guards are stored. 

This holder servers two of the simple sticks and can be screwed with a M4 2.5cm screw to the plastic rail of the PWB600. Of course, the workbench can still be folded and stored.
