Not test printed; dxf file included
Grabbed the 'V' bandaid style image off the CDC's "I got my COVID-19 Vaccine!" stickers/resources, traced bitmap in Inkscape to get a dxf and also did a quick 3d extrusion model based on that dxf (rough, not tested). I wanted to upload these for anyone who wants them.
The author marked this model as their own original creation. Imported from Thingiverse.
