sensor plugs for UJF-3042/6042 MkIIe

a tiny but powerful hack i couldn't live without!  If you own a Mimaki UJF-3042 MkIIe UV printer you probably realize that the sensor on the main cover are very annoying and even the technician suggest you squeeze a cardboard in place to bloc,  them but then you can't close the cover!! Well now,  thanks to these carefully designed plugs, you can continue to operate your printed normally (i.e. open and close the cover whenever you want) without interruption to the printers workings. 

Simply insert the by the sensor opening and use a wide flat screwdriver to wedge them into place, the will perfectly stay in place on the thick metal frame while allow free movement of the door (see animation)
