sliding door nozzle for Dyson V6

We have a sliding glass front on the veranda, rolling on 4 rails an collecting leaves and other bits from the garden. Yes, you could vacuum each individual slot with a thin nozzle, but who's got time for that?

The rails a are 4 mm wide, with a 15mm slot in between. I left a mm more on each side.
The nail polish is optional.

I used the interface part from Max or thomers, can't rember, but was inspired by both. and designed the rest on top from scratch.
