Spring-loaded Adjustable Tablet or Phone Holder for DJI Mavic Pro RC Controller To assemble this adjustable holder, use a 1/4 x 20 x 1 1/2 in socket head bolt and a 1/4 x 20 nut for the knob. The print orientation is exactly as shown in the pictures. A 3" tension spring provides the necessary flexibility to adjust its tightness by stretching it. This spring fits snugly between two holes, which can be secured using your preferred method. I used some rivets and trimmed them to size, also applying CA to the pin to prevent it from coming loose. This adjustable holder works flawlessly on a tabletop as well.
