In our office at school we have a service desk. People often have to write someting down ... Using the same pen for everyone didn't seem safe so I designed a pen holder where one side contains the disinfected pens and the other side holds the used pens.
I added a version without text zo you can add your own …
TIP:
The disinfected pens are put upside down because the pens stopped working if the point was soked in disinfecting liquid dripping down.
Dual color was achieved by a filament change after the baseplate
