HSW Bambu Hotend x4 Holder

Micha has this nice little Bambu Hotend holder for Honeycomb storage wall, and I want to store multiple hotend but don't want to use up too much space. 

So we now have a 4x hotend holder. Hopefully that is enough for most general usage.. Bambu does not yet have that many hotend size anyway. 

Best print direction would be up right, where the holder's opening facing up.
