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
