Hose adapter wall mount

I needed a simple solution for connecting my various lasercutter fume extraction hoses to the same ventilator. 

The requirements were that it should be compact, wall-mounted, and capable of supporting a 100mm hose and a 70mm hose. 

The adapters easily slide into the wall mount from the front for the top and bottom hose.
When I use another laser cutter I just swap the bottom adapter with the hose of the active lasercutter.

The adapters and wall mount have sufficient clearance to allow for the use of duct tape or similarly thick tape to stick to the bottom side of the adapters.
By doing this, the connection should be airtight and prevent any air from being drawn in. 

Although I am considering designing a version with an air lock, I currently have no need for it. Let me know in case you're interested. 

There's also an extra connector to connect two 70mm hoses to each other (I cut one to short and didn't want to buy a new one)

The wall mount is printed on the side which is mounted to the wall, or other files can be printed flat.
