I made a holder for my old lights because the original latch was broken.
I think they are Eiops CL500 but i'm not sure. You have to remove the original latch completely for the light to fit into the case. Printed with tree supports.
Small print that allows you to attach one part with zipties to the bike and still being able to remove the light for recharging.
The author marked this model as their own original creation.
