Bag Clip with automatic snap-in mechanism

General information

Version 2 with a slightly reinforced clamping section is out. See here: https://www.printables.com/de/model/234619-bag-clip-v2-with-automatic-snap-in-mechanism

Object Description:

Inspired by our bought bag clip which is not usable because of extreme thin film hinges, I transferred the only good design point of it to my already existing bag clip with strong hinges.

I removed the hinge based closing mechanism and replaced it by a automatic snap-in design.

The clip can be opened and closed now with only one hand. A great advantage if you have only one, which I hope is not the case.

If you prefer the manual locking mechanism, this version is still available here:

Advantages:

- Stable hinge

- Wobble-free hinge design

- Allows one hand operation

- It clamps reliably even thin bags

- Marble pattern in the grip zone for a better finger grip

- The snap-in mechanism works very well with PLA

Comments:

- Print the clip on the side as suggested in the data file. There are small supports in the hinge that would not work if you turn the clip on the top side.

- After printing, the hinges must be broken loose.

- After bending back and forth several times, the hinges turn much smoother.

- The design is made for a layer height of 0.2mm. Other layer heights have not been tested. Comments about successful or unsuccessful prints in other layer heights are welcome and will be added to the object description later.

- The offered lengths should be sufficient for most users. If there is a need for other lengths, please leave me a comment.

Update 2023-02-03:

• I tested the new experimental feature "extra perimeters on overhangs" introduced with Prusa Slicer 2.6.0-alpha2. Basically it works, but I don't recommend it for this clip design. Even after many back and forth movements of the hinge, it does not move as smoothly as usual.

Update 2022-03-26:

• Short model with 5mm length for test reasons added. See folder Test-file.

Update 2022-03-29:
