This shock mount has interchangeable tripod mounting rail and handle. The pieces just slide and hold together tightly. If you don't need the tripod rail don't print it. Likewise the handle. The handle STL file is a little different from the one in the photo, but it will fit just fine. They were taken from one of my other projects. Print with your favorite ABS, 0.2mm layers, 40% infill, 2 or 3 layer walls, no raft, no brim, no support needed. The rail and handle fit tightly into the shock mount frame- work them back and forth a few times to loosen them up just a little. You might consider running a file over the edges of the rail and handle to allow easier fit, but don't over do it!
