Super cheap Indoor FPV gates and towers from 14mm PVC tubes

thingiverse

Create affordable indoor FPV gates and towers using 14mm PVC pipes readily available at local hardware stores or online at a low cost. Both gates and towers can be built with just one type of part, reducing complexity. Excellent layer adhesion is necessary; consider printing at slightly higher temperatures for optimal results. While not suitable for heavier and more powerful outdoor quadcopters, feel free to experiment. To account for variations in pipe diameter between vendors, print a single piece for testing and adjust the fit if needed. If necessary, resize the part accordingly. I printed mine in PLA with 3 outer perimeters and 33% infill for optimal structural integrity.
