About this 3D model

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.
