2 Alan keys and hotend assembly box for Bambu Lab P1 X1

Box for 4 Bambu Lab P1 X1 hotend assemblies (see original) and 2 Alan Keys (Remix part). 

Slit on the back for the big Alan key(tight fit)
front for the small one.
I made the front holder smaller than on the image, because the wall became too thin on the edges.
(see also: Multiboard box for hotend assembly box / printables version)
UPDATE:
made the slot on the sides wider, so they have small holes on the side walls.
Old version risk to break the top if the Alan key was not correct inserted.
