V0 Electronics Cooling Fan (fixed)

Reopening #551 with the requested update. Please see Further Notes below for details.

I noticed my V0.1 was getting a few problems with overheating so I decided to do something about it. I made a fan duct using a 24V 3010 blower fan and a small circuit board to control it This seems to work quite well so far in my testing.

I am releasing this modification under GPLv3 in the hopes that it'll help others in the future.

[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?

printer_mods/kaze/voron0-pi-fan - A little blower fan (and ducting) to add cooling to the electronics bay of a V0.1.

How was it tested?

It is installed and running on V0.1084, complete with the recommended configuration values.

Any background context you want to provide?

This is to hopefully encourage airflow in the electronics bay of the V0.1, as I noticed I was getting temperature warnings in Fluidd.

Screenshots (if appropriate)

Further notes

This includes a custom circuit board because I could not find extra GPIOs on the MCU. The circuit board can be ordered from JLCPCB complete with the surface-mount components. Unfortunately, this uses EasyEDA for the circuit design, as I could not figure out how to get KiCad to export the BOM and Pick&Place files for the surface mount components.

Outstanding Issue from #551

jlas1's comment:

The only issue i can see on the STL's is the fan_housing.stl touching the bed with a curved surface, should be changed to make sure that there is no angle lower than 45 degrees touching the bed.

I changed fan_duct.stl to ensure there were only 45-degree angles touching the bed of the printer. (fan_housing.stl doesn't have the geometry referenced in jlas1's comment.)
