I designed this for my Gen-4 Full Spectrum Hobby Laser. I wanted to be able to monitor coolant flow and didn't like the larger version sold on the likes of Amazon. This pretty compact, and uses pretty standard "maker" tools and materials. I think it could all be 3D Printed even though I CNC Machined the body (two setups). It was a quick little project only taking a couple hours to complete. The barbs for the two coolant connections are press if plastic double barbs, I believe they were Ø0.250". Make the two holes the size required to press in one side of the barb, leave the inside portion long as it can be trimmed to fit the inside hole perfectly
