This I constrained to always lie on the center vertical line. I measured the max internal distance corner to corner and drew two crossing lines which were dimensioned, and I added a cross point that sat where they intersected. My idea was to try to measure in a reliable/plottable way, any distances out to the inside edges from the rectangle and hope I had enough resulting points to be able to fit a curve to it. Dunno if I've pulled off a good match until we can visit my other friend with the 3D printer but my approach was to work outwards from the only good reference point, the funny grippy grill bit.įiguring out the curves was not something I'm good at. So the challenge was to try to measure and design a mirrored version of the existing one.īut where to start? This thing was all curves with hardly any reference points. My friend bought a rare 2nd hand roof rack on Saturday but when home, realised one of the rubber pads that go between the metal roof rack foot and the curved car roof was missing. Was quite the measuring/figuring out challenge. Something I made for a friend over the weekend.
