NA Keytags

This is a Narcotics Anoymous Keytag. Can print in any color combo, and any amount of clean time.

It uses 25mm or 1 inch key rings. Here are some at Amazon: https://www.amazon.com/dp/B0C4KRYZ1W?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

I updated it to handle the M4x5mm Chicago Screws, by opening the screw/rivet holes a little bit. The Chicogo screws can be found on Amazon here: https://www.amazon.com/dp/B0CYZZTGF3?ref=ppx_yo2ov_dt_b_fed_asin_title

To update the clean Time

The fonts are Oswald-SemiBold: https://fonts.google.com/specimen/Oswald

• Open the "keytag.FCStd" file in FreeCad (instructions_1.png)
• Delete Fusion, Chamfer, and Cut. (It should now look like instructions_2.png)
• Download the Oswald-SemiBold fonts from: https://fonts.google.com/specimen/Oswald
• In Each "front_letters | Extrude | S " entry (instructions_3.png)
  • Click the "..." button to the right of the "font file"
  • Select the "Oswald-SemiBold.ttf" font file from the files you downloaded
  • Click "Open" and "OK" (instructions_4.png)
• Click on "Original Tag | front_letters | Extrude004 | S time"
  • Change the "String" and click "OK" (instructions_5.png)
• Troubleshooting.
  • If anything apears invisible select the item and click on "View | Visiblity | Toggle Visibility"
  • You should be able to drag items around so the view matches the instruction images.
  • If a blue checkmark appears right click on it and choose "Recompute object"
• Re-assemble the objects
  • Select the "Part" workbench in the menu bar.
  • Ctrl Click first "tag" and then "front_letters".
    • Next click the "Cut" button. (instructions_6.png)
  • Click on "Cut" and the "chamfer" button. (instructions_7.png)
    • Select one edge from the front and one from the back of the "Cut" object.
    • Click "OK" (instructions_8.png)
  • Ctrl Click "strap" and "Chamfer", and then click on the "Union" button. (instructions_9.png)
• Export the "*.stl" file
  • Select the "Fusion" object and "File | Export" and "Files of type: STL Mesh (.stl .ast)"
  • Place the file somewhere you can find it so you can slice and print it. (instructions_10.png)

• Save the updated "keytag.FCStd" file

• I am using the Sovol SV06 with Marlin
  • The Line I use to change the fillament color is
    ;BEGIN Filament Change
    M600 E30.00 U300.00 X0.00 Y0.00
    ;END Filament Change
  • In any of the slicers, first slice the object the way you want it.
    • Next
      • In Orca Slicer or Prusa Slicer, this line goes at the line where the new color will be.
        "0.64" and "2.64"
      • Cura has a color change option built in.

I like to print in multiple colors, so the text indentation in highlighted, by printing a single layer of an offset color at the bottom of the text indentations.

The way I do multiple colors in the "Cura" slicer is to:

• First open the stl file and slice it (it is most likely 4mm nozzle with 2mm layer hight)
• Navigate to Extensions | Post Processing | Modify G-Code | Add Script | Filament Change | Layer
• The numbers need to be "4, 5, 11, 12"
• Now Slice and "Save to Disk"
• While printing, it will pause and change filament, at the correct places to add one layer of the highlight color on each side of the text.

Recent changes:
Made letters a little larger, so they are more legible.
Corrected orientation of NA logo, so it is no longer reversed.
