Portable Solder Fume Extractor

This is a remix of lewosh's battery operated solder fume extractor. I made the following changes:

• Base: Closed the opening for the battery status indicator and removed built-in support structures (I prefer to use PrusaSlicer organic supports)
• Base Front: Closed the opening for the status LED reduced width by 0.5 mm for an easier fit into the base
• Base Bottom: Closed the opening for the battery compartment and associated screw holes
• Fan Housing, Fan Filter Compartment, & Fan Filter Housing: 
  • Moved cord hole to opposite side to reverse the fan orientation (pull air in through filter rather than push air out through filter)
  • Removed filter installation slot and changed so the filter (and filter compartment) just sits inside between the fan housing and fan filter compartment
  • Added screw holes in the corners to allow for assembly with four M3 x 50 mm screws & M3 nuts

Parts:

• PWM Motor Speed Controller
• 5.5 x 2.5 mm Female Socket Panel Mount Connector
• KCD1 2 Pin 250V 3A SPST Black Boat Switch 21x15
• Noctua NF-F12 iPPC 3000 PWM Cooling Case Fan
• 12V 1A Power Supply, 100-240V AC to DC 12 V
• Activated Carbon Filter (needed trimming to fit)
• M4 Heat Set Inserts
• M4 Screws
• M3 x 50 screws & M3 nuts
