A simple, one-piece bag clip with a built-in spring and a snap latch. Fold the bag top, squeeze the jaws together and push the tip under the latch hook. To open, press the thumb tab on the latch away from the clip. It prints flat in one piece with no supports and no assembly.
Sizes
S: 60 mm jaws (70 mm overall), 10 mm tall, for snack bags and spice pouches
M: 90 mm jaws (100 mm overall), 12 mm tall, for chips and coffee
L: 120 mm jaws (131 mm overall), 12 mm tall, for frozen veg and cereal liners
XL: 150 mm jaws (161 mm overall), 14 mm tall, for big bags of pet food or flour
Design
The clip prints slightly open. Closing it flexes the C-shaped spring at the back, so it springs open by itself when you release the latch
Wavy, interlocking grip jaws hold thin bag material without slipping
The latch hook overlaps the jaw tip by 0.8 mm and pulls it 0.5 mm past parallel, so the jaws clamp the bag
The latch post is extra long (about 9-12 mm of free length) to keep the bending strain low
It's a single extruded profile with vertical walls, so it has no overhangs at all
Print settings
PETG recommended. It handles repeated flexing of the spring and latch better than PLA. PLA works too but feels stiffer and may fatigue sooner
Print flat as oriented, 0.2 mm layers, 3-4 walls, 100% infill (the parts are thin), no supports
Use elephant-foot compensation or a calibrated first layer so the jaws and the latch slot don't fuse at the bed
About 3-12 g each (estimated)
These haven't been print-tested yet. If the latch is too tight or too loose on your printer, let me know in the comments and I'll post a tuned version.
If you print one, please post a Make with a photo. It really helps, and I read every comment. Questions or fit issues? Leave a comment and I'll take a look.
