How to Print Before explaining the prints, I want to mention that the O3 unit and VTX is sit inside the BetaFPV PAVO 20 VTX chassis which is NOT provided in the print file. You need to purchase one of this to complete the drone. There maybe 3D printed alternatives but I haven't tested any of them. BetaFPV PAVO 20 Chassis

Please Note:

- The frame was designed to print without infill, infill add little to no strength in this frame.

- The frame is optimzed for the placement and rotation in the print file.

- The supports in the print file are painted and are nessessary for better edges and surface finishs.
