Heavy double hinge handcuffs

The model is designed for a 0.4mm nozzle. 
Other nozzles can of course also be used, but the function can suffer as a result. I used super glue to glue the connections. If you find a better glue let me know.
 

If you find an error in the model or have an idea for an improvement, let me know and I will change and upload the new model.
