Summary

CleanOA is a door opener and is designed to open doors in public places without having to directly touch the handle with your hands. This prevents possible contamination through contact.
The front part allows to lock and unlock toilet doors. It can also be used to press buttons (switches, keyboards, etc...) without using your finger.

The design is inspired by the logo of Open Access, an international movement that seeks to provide free and open online access to academic information, such as publications and data. Wikipedia

In order to obtain the colour alternance, it is necessary to change the filament during printing with a simple extruder.
With 0.2mm layers, it is necessary to change:
-from orange to black at 2.2mm height (11th layer) and
-from black to orange at 4.0mm (20th layer).

How I Designed This

I used Onshape (https://cad.onshape.com/) to design CleanOA.
