Bag Clip

Here’s my take on a coffee (and more) bag clip with a minimalist design.
 

CAUTION! PLEASE READ BEFORE PRINTING

Please note that if you change any settings in the printing profile or use your own profile, I cannot guarantee that the print will turn out well. I strongly recommend using PETG filament to print this model. PLA does not have enough strength and may break quickly. 
 

Successfully tested on A1 Mini & PETG only
I tested this design only with PETG filament on my A1 Mini, so I cannot promise that other filaments or printers will work as well. Some people experienced fused hinge. 

PRINT-IN-PLACE HINGE

To release the hinge, apply a gradual back-and-forth force. Avoid using direct, straight force because it can break the hinge.

If you are using your own printing profile, I highly recommend adding a 100% infill modifier for the hinge and six walls.
