Description

This is a simple adapter designed to bridge the gap between a 2.5-inch port and a 2-inch exhaust hose. Originally designed to vent my 3D printer enclosure, this transition allows for a snug fit to keep your workspace fume-free.

Key Features:

  • Slip-Over Design: The 2.5" side is designed to slide over a standard 2.5" rigid port or fitting.
  • Reduction Side: The 2" side accepts a standard 2" flexible hose over the exterior.
  • Tinker-Friendly: Created in Tinkercad with thin walls (.1") for a quick print, dont over tighten any hose clamps. 

Print Settings:

  • Material: I printed this in PLA 2.0
  • Walls/Perimeters: 3–4 (This ensures the adapter is airtight and strong enough to handle hose clamps).
  • Supports: None required if printed with the larger 2.5" side on the build plate.
