DJI Mini 3 3 Pro is an excellent mini drone, but it didn't come with a prop blade holder like the mini2. All the designs on thingiverse were too bulky, so i designed something much much smaller, and compact. It seems to work well, and allows the blades not to move in transit, and i think it should fit in most cases (my fly more case, as well as 3rd party cases haven't arrived, so it's not tested in those yet), but at least it doesn't move around when i fold the wings and bring it places. I hope you like it! This was designed totally in tinkercad! video of how to use it - https://youtube.com/shorts/c_ldVcYaDqM?feature=share
