Conical adapters for Chinese turbo!!!

For a personal, handcrafted motor enthusiast project, I need a pseudo-supercharger for a seven-piston rotary engine. Let's get straight to the point: I need to connect the turbo to the carburetor and then to the engine. The output of the brushless turbo goes to the intake manifold of my 2-stroke engine. On the other side of the turbo, or pseudo-turbo if you prefer, the intake duct of the carburetor, which is 34mm in diameter, will be connected. In short, these are two cones; said like that, it might seem trivial, but it's not, because they have a specific function. The same goes for the cap that protects the brushless contacts. It's all printed with my faithful Bambu A1 and the filament used is PETG, resistant to gasoline fumes and heat, which in any case will never be excessive. During the first tests, I encountered a problem: the fan (which has nothing to do with Garretts) was touching the initial support. I therefore temporarily inserted spacers; the definitive piece to correct the problem has already been designed and is ready for printing. I won't elaborate further, but I must say I am truly satisfied. Some say it won't work, but in my case it will: seeing is believing. Let me know your opinions or any tests. Thank you very much.
