xTool AP2 duct splitter/extender

About the kit

This is version 2 of my previous duct splitter kit. The kit now has 2 new manifolds:

• a triple branch for connecting 2 63mm pipes and 1 80mm pipe (M1U, F1 and F2 Ultra UV)
• a dual branch for connecting 1 63mm pipe and 1 80mm pipe (M1U/F1 and F2 Ultra UV) 

I have also revised the 2 branch dual 63mm to streamline the inlets and tidied up the 3MF build plate structure.

There are individual blast door assemblies for the M1U, F1 and F2U UV, allowing them to be isolated to prevent suction loss.

Contents

The kit comprises:

• 80mm elbow duct for the AP2 inlet port 
• 1 triple manifold for 2x63mm and 1x80mm pipes
• 1 dual manifold for 1x63mm and 1x80mm pipes
• 1 dual manifold for 2x63mm pipes
• F2 Ultra UV blast door assembly
• M1 Ultra blast door assembly
• F1 blast door assembly

Additional parts required: 

• 4x6mm M3 bolts and nuts for each blast door assembly
• Standard xTool 63mm/80mm pipe ends

Printing

I've printed mine in PLA on the Bambu P1P(S).

• Layer height: 0.2mm
• Wall loops: 6
• 25% infill

The elbow duct should ideally be printed with the 80mm end on the build plate. I used tree supports but found the aperture deformed, so used full supports with a 40 degree tolerance.
