Customisable Zipper Marker / Bag Icons

I designed these little coins with icons on them in order to mark my packing cubes and organizer bags when I'm travelling.

I use small circular carabiners off eBay to attach the coin-markers to the zipper pulls of my bags.

I used icons from https://www.svgrepo.com where you can find many great icons.

How To Print:

Option A:

You can find some premade coins with icons I find useful in the STLs folder. Import them into your slicer, set up color changes at 0.8 mm and 1.6 mm, and print.

Option B:

Use the coinset.3mf file to print the whole set of coins. This file includes filament changes and print settings that worked well for me on my Anycubic i3 Mega S. However it might not be ideal for your printer.

General Tips:

• How to set up color changes in Prusa Slicer: https://help.prusa3d.com/article/color-change_1687
• under the “print settings” tab, set your skirt height to 200 layers, Brim type to outer brim and loops to 2. This ensures that the nozzle gets primed correctly after each color change.
• I would recommend to print as many of them at once as you can in order to minimize the number of filament changes you need to do.

How to make your own coins:

1. Install OpenSCAD
2. Find an SVG that you want to use. SVG Repo has a vast catalog of Icons available for free. Of course you can also use any other SVG file.
   Ideally your SVG is single color and uses mostly large areas with no fine lines.
3. Open the included icon_coin.scad file in OpenSCAD. A window pops up with a text editor.
4. In line 3 of the text editor replace “filename.svg” with the full name of the file you want to use. (make sure to keep the quotes and .svg)
5. press F5 to get a preview of your coin
6. If the icon does not fit on the coin i recommend to rescale it using a vector graphigs program like Inkscape or Affinity Designer, afterwards press F5 again to refresh the preview
7. If you are happy with your coin press F6 to render  it in full detail (depending on the complexity of your icon and your PC this might take a minute, you should see a progress bar in the bottom left of the window and hear a sound when it is done)
8. press F7 to export the STL of your coin and print it as described above

Bonus-tip: lines 5 to 10 define some other parameters that you can change to customize and resize your coins.
