Remake BetaFPV Pavo 20 whoop duct 3d printed.

Why 3d print the duct

The original whoop duct cost $4 but your printed one is even cheaper ;-) also with different colors and to try different materials!

Pavo20 has a molded frame with PA12 material. It is quite heavy. Here is a free version of it.

It is not reverse engineering the original frame but fleshly design.

The original whoop weighed 13.8g.

There are 2 versions

• Lite: single wall, weighed 9.6 grams, 4 grams lighter than original molded frame.
• Strong: 2 walls, weighed the same as original whoop but stronger.

Original frame dimension from BetaFPV website.

Suggested materials:

• PETG-CF
• PLA-CF
• PC

PETG has a very similar mechanical properties to the orginal PA12 but when it with CF, it loads much better.

You can also try with PLA for prototypes.

You will need 4 m2 screw inserts with diameter 3 or 3.2 mm.

Use heat insert by soldering iron or screw driver heated by a lighter. Press from top until it is the same level as the plastic part.
