This is a 3D printed PETG part designed to slide and snap into the original hole of the (coast to coast) triple water filler door (210 x135) fitted on most jayco vans. 

The original door allowing access to the centre of the main door is a living hinge and breaks of over time. The only alternative is to buy a new door or leave open to elements.

This tab will fill the gap as a quick and cheap alternative rather than replacing door a number of times over the vans lifteime.

NOTE: If you wish to leave a hose connected it would be more practical to leave the door completely open rather than removing infill tab all the time or use water from tanks via normal 12V pump operation.

Have a look on my face book page.
