About this 3D model

I got sick of having the landing gear / motor / props showing up in my pictures. So I decided to make the upgrade to a h-frame based design. This design uses Home Depot towel bar. The towel bar is 15.5mm square. This frame is designed for two 18in bars and one 30 inch bar. You only need to cut the 30in bar in half. It is used for the center bars. The 18in bars are used for the motor mounts. The top plates get secured to the bottom plates with a 3mm or 4mm bolt. The nut goes on the bottom.
