Print Instructions & Special Considerations

• Coupler - 3 walls, infill doesn't matter. 
  • Inner diameter for tube side is 31.05mm.
  • Inner diameter for flashlight side is 21.1mm.  
  • It's better to go looser than too tight as you can use tape to build it up to friction fit.

  • The hilt cap moves so that you can press the button on the bottom of the flashlight.  Clearance between the pieces is 0.3mm.
• Cap
  • Use a transparent filament such as PETG
  • 0% infill
  • 8 top layers to ensure top is covered
