I wear suspenders that have metal clips on the ends. Sometimes the clips break. These hooks slide into the loop of suspender material right at the end of any part of it. They hook onto a belt loop.
These hooks are designed for 50mm wide bands.
In the back, some pants have a center belt loop but the suspenders have two hooks on the end. If a back clip breaks, I move a clip from the front to the back so I still have two clips on the back. Then I remove the other clip on the front and just use two hooks on the front.
I used 3 perimeters and 25% gyroid infill. Printed in PLA these are very strong. They print fast without supports in less than 20 minutes each.
Credit for the idea to Michael Bergen, who showed me his 3D printed PLA suspender hooks today.
