4in Dust Collector Swivel Quick Connect

This is a dust collector quick connector for 4 inch ID hoses, inspired from the Rockler Quick Connect.

I tried the various magnet-based quick connectors and find them to be cool, but too easy to get disconnected (not enough magnetic hold), especially when the pipes are somewhat heavy and stretched/at-an-angle.

Friction fit is the best interface. 

Features:

• 2.5 degree interface angle with 40mm mating surface: loads of grip
• fits 4in ID hoses, eg, the diameter of the printed connector is 101.6mm (tested fit with Lee Valley 4 inch polyurethane dust hose)
• swivel joint - allows the pipe to rotate freely at the joint

Included Components/Adapters:

• SawStop Jobsite Saw dust port (65mm/2.5inch OD port)
• Extension swivel - extend any number of 4in ID hoses with the hoses freely rotating on its own
• Wall hanger for quick connector - holds the whole thing upright and pipes neatly out of your way
• more will be added in future as I expand my dust collection system

Print Instructions:

• Fits Bambu Labs x1c/p1p/p1s printers
• note that the files often contains multiple objects, model viewers shows the assembled version. Set your print plates accordingly
• Generally speaking:
  • 0.4mm nozzle
  • ABS or PETG preferred for strength, PLA works too. Be careful with ABS shrinking, this is dimensioned exactly
  • 4 perimeter
  • 15% infill
• Quick Connector settings:
  • Print with the interface opening facing down on the build plate, angled 45 degrees (see pictures)
  • Tree support, 40 degree threshold angle
  • 10mm brim
• Wall hanger settings:
  • horizontal on mounting interface
  • support enabled, make sure the rods are printed horizontally and not vertically (for strength and layer adhesion

Assembly:

• glue the swivel holder to the main body with the hose connector inside
• be careful to not glue the hose connector

Interface dimensions to design your own adapters:

• ID 48.30mm (4inch ID hose - 2.5mm wall thickness)
• thickness start: 1mm
• 2.5 degree angle outwards
• 40mm length of interface
• (revolve tool around axis in fusion 360, should be extremely easy to replicate)

Included the Fusion 360 files

Changelog:

• Oct 17 2023 - added wall hanger for quick connector
• Oct 16 2023 - added swivel extension, refactored designs into components and cleaned it up
