Basic Carabiner for messenger bags
thingiverse
My bag's strap carabiner worn down because of the friction between 2 movable part. I decided to give 3D printing a try for a heavy duty purpose. IMPORTANT. Model is designed so you can fit a 5mm diameter fitting part inside the hole. I put it inside the hole as an insert while extruder was high enough so it would't collide with the piece and ruin the print. Only thing I can say is that the part has been doing very well on both sides of my messenger bag. Almost daily I carry about 5-6 KG in it. Printed with PETG from MG Chemical's. Maybe you will fin this inspirational and create you own remix. :D
