Missing part

[Bryanne]

Hello there this is my first time posting as I'm a new bongo owner. My roof alarm beeps constantly while the roof is down. I've sussed out the problem, I am missing the plastic bit that presses on to the roof sensor on the front, nearside of the vehicle (see picture of the drivers side). Does anyone know what it's called? Where I might be able to buy one? Or does anyone have a 3d printer they could print one with? TIA
