The center sleeve is made to hold both the mask/filter pieces, using the pressure of the two outer shell part being screwed in together around the sleeve.

This repository also provides a _plug_ to use instead of a canister for masks that have two threads for canister - _like the one we provide at_ [distorsion/3D-printed-parametric-gaz-mask](https://git.deuxfleurs.fr/distorsion/3D-printed-parametric-gaz-mask) - which you can print from the [3Dfiles/nato_thread_plug.stl](./3Dfiles/) file.

## 2 - Assembly
|
||||
|
||||
Once you have printed all the requiered pieces as described in the [_3D printing section_](#3-3d-printing), the assembly is simply done in three steps :
|
||||
|
||||
<img src="https://git.deuxfleurs.fr/distorsion/3D-printed-parametric-40mm-gaz-mask-canister/media/branch/main/pictures/canister_asembly_step1.png?raw=true" alt="Image not available" height="300" />

|
||||
|
||||
You can first put your (_covid/chirurgical_) mask or filter and put it in the _cap_ or at the top of the _sleeve_, with 0.5/1cm extra material all around the _sleeve_.
|
||||
|
||||

|
||||
|
||||
Secondly, you can push in the _sleeve_ within the _cap_ making sure that the whole surface of the mask/filter is fermly held and that there are no holes.
|
||||
|
||||
You can then fill the _sleeve_ with your filter material : typicaly activated charcoal which can be source **cheaply** from activated charcoal for aquarium filter.
|
||||

||||

|
||||
|
||||
Finally you can repeat the first step with the top of the _sleeve_, putting a mask/filter, then pushing the _sleeve_/_cap_ assembly into the _main body_ before screwing the _cap_ and _main body_ together, thus securly holding the sleeve and he two mask/filter holding the filtering material in place.

|
||||
|
||||
To assemble a full canister, you need to need to print :
|
||||
- 1 _sleeve_ from [3Dfiles/canister_sleeve.stl](./3Dfiles/)
|
||||
- 1 _cap_ from [3Dfiles/canister_cap.stl](./3Dfiles/)
|
||||
- 1 _main body_ from [3Dfiles/canister_main_body.stl](./3Dfiles/)
|
||||
|
||||
You can also print a _plug_ to use instead of a canister for masks that have two threads for canister - _like the one we provide at_ [distorsion/3D-printed-parametric-gaz-mask](https://git.deuxfleurs.fr/distorsion/3D-printed-parametric-gaz-mask) - which you can print from the [3Dfiles/nato_thread_plug.stl](./3Dfiles/) file.

- print the _plug_ ([3Dfiles/nato_thread_plug.stl](./3Dfiles/)) with the flat face facing down.

|

If you want to changes the parameters of this design, you can edit the _Freecad_ file [3Dfiles/40mm_gaz_mask_canister.FCStd](./3Dfiles/), which is fully parametric, with parameters present in the **Spreadsheet**.

If you want/need to change parameters, we would suggest you play with them and try to understand the impact of each parameters. We will only explain a small selection of important parameters that you are most likely to have to edit.
