I have a Hanuman/Hawk with a Jabiru 2200 engine on it. Not being its first owner, I ran into a problem, specifically, one of the previous owners had lost the intake airbox and replaced it with a section of scat hose which was then run to a filter. This worked fine for several years, but as the hose has aged, it has become problematic.
Doing some looking online, I realized that the factory designed an airbox that fits in the tiny space between the carb and the firewall, that I did not have. I know that the best solution would be to purchase an airbox from the factory, however, I have not been able to get a response from them for several years. As such, I took it upon myself to address the issue and designed and 3d printed an airbox and intake pipe for the plane. I then printed it in a high-grade engineering nylon. So far, it seems pretty good; it's very light too.
Obviously, this falls squarely in the territory of experimental aviation, but it occurred to me that I might not be the only person who had this problem or could use this, so I published the files on thingiverse for anyone to use.
I realize that no one else in the group might need or want the files, but on the off chance someone did, I figured I'd let you guys know in case it helped anyone else.
