My sister likes to sew and often bags. The problem is, that even cheap D-rings with no design often costs way to much and those costs add up. So I've opened Fusion 360, created a simple version of it, and printed it in PETG.
Sister was happy with the design but was concerned about the carrying capacity. So I quickly filled a watering can with 10 liters of water, grabbed a thin rope, connected the things together and lifted it without problems. There was no deformation. 10kg without problems - that was okay for her ;-)
