Thicker Wall Version: (https://www.thingiverse.com/thing:3837165)
Inspired by rich1051414's 40mm fan duct with zip tie straps.
I liked the idea of having a zip tie secure the fan duct to the e3d radiator fins on the 40mm fan duct model so I thought i would make my own model for a 30mm fan since i wasn't able to find one.
You will need one 1 standard size zip tie to secure the fan duct to the radiator fins.
Any Annealed PLA
If you plan to use PLA with this print I recommend you anneal the fan duct for at least 30 minutes before the first use
Make sure not to over tighten the zip tie. Finger tight will do just fine
