Expensive, but 100% worth it...
I'm a VERY AMATEUR 3D printer, and tried making this reducer and just couldn't get it right. I knew I was going to buy this if I couldn't get my own print to work.  After failing 3 times, I bought it.  It is super expensive for the amount of filament used to make this (maybe 0.30 cent worth?), but you're more paying for the creators time and skill (and shipping cost).<br /><br />But I will say, the quality is top.  I really like how snug it fits.  I use it on an inline fan to vent my laser printer, and I have zero smell, and perfect ventilation with no leaks.  So, well done!  Highly recommend if you can afford it.
