• AVR studio and microchip studio


• AVRDUDE

Air Filter / Canister

• Long Running Project between Chris Kraft and Parker


• Mods on the red Jeep necessitated moving the original air cleaner


• First design was all 3D printed around 2016 / 2017
  
  
  • This is right around when 3D printing large objects like this started to get fessable on a hobby printer
  
  
  • PLA glass fiber
  
  
  • Worked but the material couldn’t handle the underhood temperatures
  
  
  
  


• Second design was welded together out of steel
  
  
  • Material was due to tool and cost constraints
  
  
  • Working to this day
  
  
  • Used a filter that is not manufactured anymore
  
  
  
  


• Third design is a combination of everything Parker has learned about 3d printing
  
  
  • Polycarbonate seems to hold up in under engine bay temperatures
    
    
    • Endcaps printed in this material
    
    
    • Heat set brass inserts for screws
    
    
    
    
  
  
  • Aluminum mounting brackets for 3” hoses 
  
  
  • Carbon fiber for the main body
