Overview

Thank you for checking out the project guide for the MUIN Fume Extractor boom mount. I like to keep as much off the desk as possible, and having the fume extractor taking up space pissed me off within 7 minutes. I designed this housing to fit around the MUIN fume extractor that can be bought on Amazon, giving me the ability to mount the extractor to a boom arm instead of having it sit on the desk. It's a 2-piece print that used a few magnets to keep the top on, allowing for easy and painless access to filtration and filters.

Tools

  1. Soldering Iron (my pick)

  2. Knife

  3. Hex Key (my pick)

  4. Phillips Head Screwdriver

Assembly Guide

While it was a little bit flimsy, it did work! I would recommend beefing it up a bit though.

Once your two parts are printed, using either a regular press or a heat press:

  1. Press all x8 5mm x 3mm magnets into their holes in each corner.

  2. Heat press all x3 1/4” heat threaded inserts into the PART A - Bottom

Note

I made the holes for the 5mm (D) magnets 5.2mm, so it should just be enough to push the magnets into place if you just wanted to put a glob of super glue in the hole. Or, you can use a head press to push the magnets into place.

Here is what the MUIN fume extractor looks like on it’s own:

Take the “PART A - BOTTOM” part and lay it flat on the desk. Take the MUIN fume extractor with the filter facing up towards you, press the fume extractor into the PART A. The bottom feet of the extractor are mean to

You can then place the filtration part and the filter on top of the MUIN.

Then push the PART B - TOP part down on top of everything. The small teeth that printed on this part keep the flimsy blue filter in place. The final product should look like this!
