Dyson extension tube wall mount (MultiClip)

I tried the original item by chenhj and liked it so much that I recreated it for the [MultiClip mounting system](https://www.thingiverse.com/thing:2747516).
So, technically this is not a remix because I recreated the object from scratch but since I made it very similar, I think it is totally deserved to mention where I took inspiration from.
