Prusa Covid-19 Face Shield with Buckle

thingiverse

I've created a modified version of the Prusa Covid-19 face shield headband (https://www.prusa3d.com/covid19/) with an added buckle instead of just a nub for attaching elastic. After printing it, I'm pleased to say that it works flawlessly, but being new to 3D modeling, I'm eager to learn if there are any ways to optimize this design. The print time seems relatively lengthy compared to the original model, so I'm open to suggestions. I designed this revised mask for two key reasons: 1. I had an abundance of regular elastic on hand without pre-punched holes, and attempting to slice it to fit over the original nub resulted in excessive fraying. This modification ensures a secure fit with normal elastic bands. 2. My wife, an ER nurse, expressed concerns about the porous nature of the standard elastic, making sanitization challenging. By incorporating a buckle, the entire assembly can be easily detached and washed separately from the mask, minimizing germs and hassle.
