Wing Harness Hook

I designed a wing harness hook inspired by the design of NSI and printed it in PETG. I used 30% infill and the part seems definitely strong enough after some uses. The space for the belt is 50mm as I used an old car seatbelt from a junkyard. I had all other parts lying at home so the harness was literally free. Alternatively you can just use a 50mm velcro band as belt which I tried before. The velcro was supplied with my wings so also no cost there.
