Plug for sealing the "useless" IdleSpeed Actuator used in many BMW engines

thingiverse

I designed a custom plug to block the opening in my M54B30 engine's intake system. After removing the Idle Speed Actuator, there was no longer any need for it, and I could repurpose the lower compartment as a cost-effective housing for a blowoff valve sourced from VW or Audi. To create this piece, I used a 3D printer with a filament that's resistant to engine oil and gasoline, such as ABS. Since I had carbon fiber filament loaded into my printer, I opted to use that instead.
