Samuel Adams (shown below) from Star EMS came to Cyb Llings Inc and GoEngineer with a design problem. He wanted to make an adaptor that would convert a snorkel mask into a respirator to help beat COVID-19. With the partnership of CAD, computer simulation, and 3D printing experience, we were able to get a working prototype in less than 24 hours and over the course of a week of tweaking and fine-tuning, it passed a qualitative fit test.
Having the snorkel mask in hand and a pair of digital calipers made it easy to replicate the portion of the mask that the adaptor needed to fit.
Once the dimensions were determined for the proper fit of the adaptor, the remaining design still needed to satisfy two constraints:
We used SOLIDWORKS to create the design below.
With the use of Cyb Llings’ Connex 3D printer, we printed and tested many versions of this design to make sure it fit correctly with seals.
The image below shows a detailed view of the filter region and how the air enters through the filter before being guided to Sam’s lungs.
About Shaun Bentley
Shaun Bentley is passionate about applied mathematics and engineering, which led him to pursue and understand real world applications of FEA, CFD, kinematics, dynamics, and 3D & 2D modeling. He teaches many simulation classes to both new and advanced users attending training at GoEngineer. Since 2006, Shaun has been working with simulation tools to solve real world engineering problems. With every new project, he seeks to find ways to push simulation to its uppermost limits, even going so far as to write bespoke code and macros. He has passed the Michigan FE exam and mentors or consults for virtually any industry that uses SOLIDWORKS, especially automotive and automated tools. He is a speed 3D modeling champion and one of the first Certified SOLIDWORKS Experts in Simulation in the world.
