QAV-210 FPV Pigtail and Receiver Antenna Mount for 3mm RC Tube

Print at a slow speed and without supports. You do not want any stringing and obstructions inside the tube holder or you will not be able to push it in. I used 3mm RC antenna tubing for this. I printed using PLA and it fit snug. I have not tested TPU yet, but you may try if you would like the added durability and flex. UPDATE: I tested TPU and it works, but the tubes felt loose so I held them in place with a ziptie.
