Low Pressure Air Reservoir for improved cutting.

Being a Hackaday fan and a laser cutter fan, I've been recommended this article about improved laser cutting many times over already. The idea is simple enough, laminar flow from the cutting nozzle appears to improve cutting performance. They don't provide a 3D model and I'm super busy so I employed my newly retired Dad to create one for me. It's a work in progress and I haven't printed it yet, we did find something very interesting along the way though. My laser cutter has a typically large aquarium pump, it's a bit of a 'puffer' and you can hear the air rushing out of the end of it in puffs, not ideal for laminar flow. Dad suggested a low pressure air reservoir to smooth some of the airflow before it goes into the laser. This really doesn't have to be very complicated and a 2L plastic bottle makes a perfect candidate. I drilled a hole through the cap and the bottom (the two thickest parts of plastic) and wedged the silicon tube into the gaps. The
