Door opener

prusaprinters

<p>This device helps improve hygiene and avoid the spreading on covid-19. To use the door opener you simply hold the bar with a thumb grip indented on the left hand side and put the thicker of the two arms behind the door handle, then bend/move the thinner of the two arms so the prongs sit above the other one from the thicker arm. Then simply pull (or twist/pull). This works for any push and pull type door and all types of door knobs.</p>
