Elegant bag clip, very strong, various sizes

I know there are a lot of nice bag clips here already, but I wasn't entirely happy with any of them, so I added another design. There are 3 sizes for clamping lengths of 65 mm, 90 mm and 120 mm.

My design goals were:

• stability,
• longevity,
• high holding power,
• easy operation,
• no notoriously weak hinges,
• easy printing,
• and last but not least a pleasant appearance.

How to use:

As a rule, it is enough to bend the clip on the closure by a maximum of 1 cm in order to slide a bag between them or to remove a bag. It is not intended to bend the clip to larger angles. Bending too hard can cause the clip to break.

To open a locked clip, please use one of the two methods shown here:

Print settings:

First of all - a flexible material must be used, such as PETG. I haven't even tried printing clips with PLA since I don't think they will work for long (PLA permanently deforms under tension).

I also recommend:

• line width 0.4 mm,
• layer height 0.2 mm,
• 3 wall lines,
• 4 floor and ceiling layers each,
• 25% zigzag infill.
• a z-seam positioned as in the print preview above.
