Hệ thống lọc nâng cao: Adjustable Exhaust (v1 & v2) cho Original Prusa Enclosure

You might want to look at my recent Adjustable Exhaust v3

Remixed the Advanced Filtration System Add-on Printable Parts to add a ducting and exhaust system that can be easily oriented to redirect airflow into or out of the enclosure

Features

• Easy to print and to assemble
• Can be easily oriented to redirect airflow into or out of the enclosure
  • Keeps the enclosure cooler while printing PLA (around 24.9°) or PETG (26.9°)
  • Keeps the enclosure warm while printing ABS or ASA
• 2 Choices of Exhaust Duct
  • 90Deg : Fits the Fan Rotated 90deg - Prusa Filtration System Housing Remix
    • Requires printing a Remix of the Advanced Filtration System Add-on
    • But provides an almost direct line ducting and better airflow  
  • Original : Fits the Original Advanced Filtration System Add-on Printable Parts
    • Reuses the existing Advanced Filtration System Add-on
    • But the ducting is curve and allows less air circulation 

What you need

• Super Glue 
• Spare nylon rivets (4x)
• M3x6 Socket Head Cap Screws (3x)
• Printed parts
  • Exhaust
  • Duct (90Deg) v2
    • Print the Fan Rotated 90deg - Prusa Filtration System Housing Remix
    • v2_duct_seg(1,2,3,4)
  • Duct (Original) v1
    • Reuses the existing Advanced Filtration System Add-on printed part
    • v1_duct_seg(1,2,3,4,5)

Be advised

• This is a tight fit, your printer and filament settings must be well calibrated
