Flat Pack Conformal Rocket Fin Rails!
thingiverse
I had to create a model rocket that would be perfect for a workshop, something I could easily transport by packing it flat into a suitcase. To make this possible, I designed these conformal rail mounts, specifically tailored to receive fins with a thickness of exactly 3.125mm. The root length of the fin mount is currently set at 100mm, but don't worry - you can adjust the FreeCAD file as needed. What's more, the radius of the fin mount is carefully designed to fit snugly into a standard 55mm postal tube, with a measurement of 27.5mm. This means it's even tight enough to hold the fins securely without using bolts, so feel free to remove those holes altogether if you prefer!
