Add THE FILTER to the mod list

• [x ] The mod, firmware configuration or slicer profile is in the correct category folder. Printable mods go to printer_mods/, firmware configurations go to firmware_configurations/, slicer profiles go to slicer_profiles/. Create a subfolder with your name, and place the mods in a subfolder with a descriptive name within that folder, e.g.: /printer_mods/FHeilmann/flux_capacitor
• [ x] Folder and file naming:
  • Folders and filenames shouldn't contain spaces. Only letters a-zA-Z, numbers 0-9, underscores _, hyphens - and periods .
  • Primary color: part_xyz.stl
  • Accent color: [a]_part_xyz.stl
  • Opaque color (Blocks light): [o]_part_xyz.stl
  • Clear/transparent color (Allows light): [c]_part_xyz.stl
  • Quantity, if more than one is needed: part_xyz_x4.stl
• [x ] For each mod, add a small README.md file to its folder with a short description of what the mod accomplishes. This readme can be used to add pictures, give assembly instructions or specify a bill of materials if the mod requires additional hardware.
• [x ] The PR modifies the top-level README.md of the category folder adding the contribution to the table. Read the top part of the file for instructions on how to do this. Please preserve the alphabetical ordering while adding new rows. Make sure to fill out the compatibility matrix to indicate which versions of the Voron printer the submission is compatible with.
• [ x] The mod/configuration/profile has been tested by the person submitting the mod and/or other Voron users. Make sure to add information about how the mod was tested below.
• [x ] The mod is not merely a slight modification of an official Voron part, configuration or profile (i.e. an official Voron part with a few mm added or removed or a slicer profile which only modifies a few values). (When in doubt, contact one of the admins in the Voron discord before submitting the PR)
• [ x] Submitted STLs are printable without support. (If the mod does not meet this criterion join the Voron discord and ask the other users for advice on how to modify the mod such that it does not require supports)
• [x ] Submitted STL files are not corrupt. (This can be tested by opening the STL in PrusaSlicer and checking if mesh errors are reported.)
• [ x] Submitted STL files are oriented and scaled properly for printing.
• [x ] Submission includes a CAD file in the form of a .STEP or .SCAD file
• [x ] Submitted firmware configs or slicer profiles contain no sensitive data (e.g. API keys).

Which mods/configurations/profiles are added by this PR?

This PR adds a mod that I dub THE FILTER. It is a activated charcoal filter that is oriented and designed to increase the temps of your printer chamber efficiently and quickly. It features custom control macros provided by Andrew Ellis with his permission and a magnetic electrical quick disconnect for easy maintenance and removal.

How was it tested?

This mod was tested through use and by measuring against the nevermore and a stock voron 2.4. It VERY quickly heats up the printer reducing preheat times extensively. To date I have 40 hours of run time and have witnessed no warp or deformation of the parts.

Any background context you want to provide?

This works really really welll!

just saw your question on the old P.R. too late to do any good: you just push more changes to the same branch you're generating the P.R. from, and the updates track through automatically.

Learned that from ellis after the fact lol

Did you have the chamber temperature sensor for these tests on the Z chain guide mount like is common? If you did this mod will blow the hot air basically directly on the sensor which I would think would massively skew the testing results. Your test results seem a little too good to me which is why I ask. The nevermore blows the air out of the front of the bed so it would need to mix with the rest of the chamber air before hitting the sensor especially with the print head parked in front of it like it normally is. This mod blows it out of the back of the bed which would hit the back wall and shoot up into the sensor. For a proper comparison it would probably need to be tested with the sensor in the top center of the print chamber.

Hi I see your input and I hear your concerns about my testing of my mod. My results are valid and here is why. I have two thermistors in my chamber one in the tool-head and one in the z chain all my testing was done with the tool-head off to not skew result. In my testing I consistently found three things consistently. 1. my heat up times are much faster 2. my chamber get much hotter then when I used the nevermore. 3. My mod doesn't melt. These are the reasons why. 5015 blower fans have relatively high static pressure compared to other fans. This makes them ideal for use in a filter that forces air through the filtration media. This high static pressure also makes for them performing poorly in the nevermore where certain design choices such as the mesh leads to excessive resistance and consequently seepage out through the gaps in the models. My mod addresses these issues it favors wide open holes for low resistance efficient airflow. It more efficiently moves and circulates air which is better for filtration and heating. It also as a unintended bonus runs more quite then the nevermore and I am using the three fan version. Simply put the following things are better. The heating, filtration, noise pollution, and maintenance are all better. My testing results are valid truly it works just that well.
