This is my take on the idea of a bag clip with a screw lid. The main benefit is that you don't need to take it off to get something out of the bag.

Why do you want my version?

• You don't need a third hand to put this on since the middle part is attached to the main hinge.
• The cap takes only 1/5 of a turn to screw/unscrew, and you can do it with one hand.
• The hinges are shared with my new Print-in-Place Bag Clip 2, which is even more robust than the first one.
• No support, no post processing, no assembly. Just put it on a bag and screw the lid on.
• It prints in about 2 hours depending on the size.
• There are multiple sizes and a source file if you want to make your own.

How to print?

• As with all bag clips, you can use PLA, but PETG will last longer.
• Make sure you have a clean and level bed
• Setting are included in the 3mf file (all standard, no support or brim needed)

How to use?

• Let it cool after printing
• The hinges will be a bit stuck, this is normal. Trying to close the clip will free them.
• Open the arms all the way
• Insert the bag between the hinge and the middle part
• Put the bag around the middle and close the arms
• Close the latch
• Put on the lid
