This is a mod to the front air vents on the XL enclosure, to allow you more choice in how you control airflow. To build it you will need:

  • 6x M3 inserts
  • 6x M3x6 screws
  • 4x M3 washers

Note I have newer model which offers adjustable front and side vents and it is available free right here.

I printed my parts in PC as I have it available, however usually this part of the printer will be cooler than everything else above, and it is mostly on the outside so PETG will probably do.

You can preview them in a web browser on a computer or in AR on a phone/tablet/headset here.

If you are mostly printing PLA, PETG, and TPU you do not need this mod typically. It is very useful for “engineering plastics” however. Keep it open if you do not need it partially or fully closed.

If you enclose your printer too much and run it too hot, you may cause damage that may not be covered under warranty. Monitor the temperature and do not let it get too hot.

Install an M3 insert in the handles.

This part has supports in the inner groove where the vent cover slides in and out. Remove them carefully.

Also there are supports in the holes where the inserts should go. Remove these so you can see the holes as pictured.

Install two inserts in each main body, one where the lower corner screw will go and one where the upper screw near the middle of the printer (i.e. diagonally).

Slide the vent cover into the main body, it should move easily in and out if you have removed the supports well.

Note the orientation of the hole in the cover and the screw mounts in the main body.

Slide the cover all the way in.

Place the knob over the hole as pictured and supporting it screw in just a screw (no washer) in the other side.

If you have thread locker it is OK to use here as probably you don't want to take it off.

Prepare 4 screws, with a washer mounted first, then a plastic spacer on each.

Install the right side using the screws you prepared earlier using these holes. 

Put the lower corner one through first, or you may have a hard time later.

Do the same for the opposite side.

Congratulations, you are done! If you find this useful please consider joining my club, if only for a month. Thank you!
