Laser exhaust with flap to close or open the air

otmar · January 21, 2019, 1:35am

I have a 4" pipe to vent the laser exhaust through the wall. But I was getting tired of connecting and disconnecting the hose to protect the laser from the air outside when I was not using it.

Here is a solution. It is a combination of 3D Printing and Glowforge laser.
I needed it to be able to connect to 4" pipe extending from the wall, connect the flexible hose from laser and to be able to close/open the air without disconnecting anything.

Here is the solution I designed:

The wood pieces are laser cut from medium draft wood. The plastic pieces are printed.

The assembly design:

Flap inserted to open the air:

Flap inserted to close the air:

3 screws to put it together:

And connect to the wall and hose:

Now you can swap the flaps to close or open the air flow.

Fun project to make life easier.

That is a great solution. Love how the Glowforge and a 3D printer can work together like this. Nice designs skills.

I love how this design works, and I needed to find a better solution that my current out the window setup. I unfortunately do not have a 3D printer, I however do have 2 4" closet flanges (toilet rings), so I may try to rig something up the same way. Thank you for sharing this.
