Materialise is an awesome 3D-printing service. In light of the COVID-crisis, they designed a suite of door handles that you could print and attach to doorhandles around your home or office, so people can open doors without touching them with their hands.
However, I found that none of their designs quite fit the most common door handles in use in The Netherlands. Also, one model tended to break easily because of the thin walls. So I adjusted their designs.
Best printed in PETG w/ 100% infill for sturdiest end results.
