Exhaust piping for Voron V2 enclosures

It is maybe easier to use a 60mm diameter aluminum duct, but it is not neardy enough.

This ecosystem allows anyone to print their exhaust ducts by themselves. There pipe connectors can directly connect to a 60mm fan, using the same screw setup. There are pipes, 45 degree corners and 90 degree corners. The exit is either 90 degree or double up-right 45 degrees. Sealing should be printed out of TPU named as ‘fan_connector_flex_pad’.

There are pipe models left and right threaded, all connector connects two of the opposite threaded pieces. It is recommended to print the corner and connector pieces out of some higher temperature plastic, not PLA. I measured over 50 degree C  in the enclosure so PLA may be risky.  All the gcodes and slicer projects set to generic PETG.

The pipes should be printed out of flexible material. All the project files and gcodes set to 0.8 mm nozzle and are printing the pipes in vase mode, which is multiple times faster than print it normally. I used 95A hardness eSun TPU, the temperatures set to this type which needs 220 C nozzle temperature. Set the temperature according to your material.

I've printed ABS and ASA using this system and so far no odor in the room. I lined the pipe right under the kitchen extractor fan and run it whenever printing stinky. Direct piping would be great but that involves two valves one for the kitchen extractor fan and one for the printer, and this I did not figure out yet.

I started this project to figure out how functions and recursion works in OpenSCAD. You can generate similar pipes by changing the parameters. The wall of the pipe is built of circular shapes connected at an angle of ‘half_module_join_angle’. The ‘module_external_radius’ determines the radius of these circular shapes. I guess the other parameters are self explaining. Unfortunately the other pieces are not parameterized.
