I tried to adapt the original born for the VZ-Bot 235 to the VZ-Bot 330

for those who have the stepper pin facing inward I added an Airbox with the lower left part recessed so as to adapt it directly without having to turn the engine, if instead you have the pin turned or you want to turn the stepper there is the classic version.

You will need more than the original project:
2 brass inserts M3x4x4
2 M3x10mm screws
for the gasket a little TPU

for the rest of the materials:

1. place the TPU gasket on the bezel;
2. fix the ring with the C-PAP;
3. attach the muffler to the airbox;
4. fix the Airbox to the ring nut.
