Replacement pieces for a cheap Chinese Respirator

thingiverse

I've been relying on a bandanna to shield myself from inhaling sawdust in the woodshop. Recently, I purchased an inexpensive Chinese respirator from SneezeBay after being too thrifty to invest in a reliable one at the local hardware store. Surprisingly, it functions fairly well most of the time, but two tiny plastic components did crack on me. Initially, I planned to glue them back together and then create an RTV mold to re-manufacture them from epoxy putty. However, after succumbing to procrastination, I decided I needed a diversion. So, I sat down and modeled them in 3D. I've printed these parts using PLA on my makerbot 2, and they work flawlessly. Meanwhile, a couple of friends offered to print them in ABS on their home printers for me, which should provide enhanced durability. Although the PLA pieces are performing adequately so far, I'm looking forward to testing the ABS versions. To facilitate replication, I've included all necessary files for these parts. I created the 3D models using Tinkercad, and they can be found on that platform as well. Printing them requires no supports or rafts, making a set of two pieces print in just over ten minutes! If anyone knows the correct nomenclature for these components, please share your knowledge so I can update my project accordingly.
