This is a design I came up with to solve a problem on my 7 inch Long Range Drone build. I had to stick the high powered VTX on the bottom of the frame, so I needed to lift up the quad in order to give the VTX clearance. I call it the “Stiletto” landing gear, for obvious reasons. I built the design around this CAD model of the GEPRC Mark 4 Frame I found on GrabCAD.  It is intended to be printed in TPU and it takes advantage of the holes in the end of the arms to make them “snap” on, so you don't need to hold them on with the motor screws. My frame is a clone frame that I got on AliExpress, and it fits great, even though I am fairly sure the CAD model I used is based on the original GEPRC frame. I made the model with baked-in supports, as I found that the supports generated in the slicer weren't very good, and left a really rough surface or were too hard to remove. Careful when your removing them though, as it is easy to accidentally rip out the “nub” that keeps the landing gear attached. I am too dumb to make parametric models, so I just made a few different versions for different heights. 10mm, 20mm, 30mm, and 40mm (pictured). I also included a STEP file so feel free to modify that to your heart's desire :)

Print in TPU with at least 15% infill, 2 perimeters, and 3 top/bottom layers.
