Antibacterial button

When using an antibacterial filament like the one advertised by Copper3D, these buttons can be stuck on top of commonly used public buttons like lift ones or outdoor crossing ones and help prevent the spread of viruses like Covid-19.

The numbered ones can be used when covering a button with a number, like in a lift. However there is also one without a number.

The diameter is 25mm with 5mm height. The design can be scaled up and down in software like meshmixer.
