About this 3D model

I wanted to try RodLaird's Rep2/2X scrubber design, but here in the USA, the specific cartridge he used isn't readily available. tempo502 mentioned a Neiko respirator cartridge available on Amazon, which had slightly different dimensions. You'll need to print some of RodLaird's original components, so please read the instructions. Your mileage may vary, proceed at your own risk. I make no statements to the effectiveness or safety of this air filtering device.
