I saw the Distance aware badges that can be collected from some shops and libraries in Scotland & Wales and thought it was a good idea so knocked up a couple of designs (one just the badge and one with holes so it can be sewn onto bags or clothes) in a few sizes. Should be extremely easily printable in a wide variety or materials, if using an above average nozzle size (+=0.6mm) make sure to disable detect thin lines and remember even with a larger nozzle you can set the slicer to make thinner lines to preserve the detail.
If using Prusaslicer it ‘should’ detect this as a badge and offer to insert the filament change on the correct layer but it's easy enough to do on your own as well.
The stitchable versions holes for thread are quite small so make sure you select external perimeters first to avoid them becoming too small.
EDIT: Added a V2 version with holes .5mm larger to allow for thicker thread.
The author marked this model as their own original creation.
