Qidi Plus 4 - 4 inch duct

Here is a duct for the Qidi Plus 4 to connect a 4 inch dryer hose to the air outlet port. No need for screws or glue, the model clips into place, insert and twist clockwise to lock.

If you are lucky enough to have a window close to your printer it is recommended to exhaust the air from your printer directly to the outside even if you use a filtration system (especially the original carbon filtration system of the printer).If you don't have this chance I have designed a more efficient filtration system combining activated carbon and a HEPA filter which fits in the same place as the original one. Here is the link:

You should print this part in ASA or ABS to prevent distortion that can occur with PLA and PETG because the air coming out of the chamber can be as high as 65 degrees Celsius (around 150F). If you only print low temperature materials that do not require heating the chamber, PLA and PETG can do the trick.

Printing is very easy, just activate the tree support that touching the build plate for the hooks. The installation on the printer should be tight, but the model was designed like this for better stability/solidity.
