These are pretty specific pieces. Not sure it is useful - maybe the Fusion 360 design files could be?
This is an elbow that accepts 6" ducting on one side, and a 8" x 3-¾" opening (+ a ¾" flange and holes for screws) on the other.
I have 2 versions:
- 1 piece design
- 2 piece design. This is the same size as the 1 piece but is split into 2 parts and requires 2x M5 threaded inserts and bolts to join.
These are long prints and need tree supports.
Why do this?
I need to add additional air returns to my HVAC system in a soffit. It is tight up there. I need 3x 6" ducts to make up enough return. The 1-piece design barely squeezes into that soffit in one location, but I had to split the elbow into 2 pieces so I can position the parts inside the soffit and then screw together. I provide both designs.
I printed in PETG. It you are printing elbows to supply air - of course you cannot use PLA because it will melt.
