Round Rack Canoe Carrier

thingiverse

Eight years ago, I posted by first design https://www.thingiverse.com/thing:27043 which was a rack stop for a square tube. At that time, I was using sketchup and ABS. I remember it was quite the hassle to design and get the first layer to stick and then to keep the ABS warm enough to avoid warping. Last weekend, I helped a friend load his canoe while parked at a slope. It was a hassle as the canoe kept sliding sideways off the rack. A quick trip to F360 and an overnight print solved this problem. I printed in PETG at 40% infill for strength. ABS or nylon would also be good. I used some bolts I had lying around. I heated up the bolts and pulled/melted them into the holes. Stainless steel will be best for this outdoor application.
