Clip — supported bag clip (all materials compatible, incl. PLA)

🧩 Description / Design Concept

Enlarged print-in-place bag clip designed for a tight, reliable seal on many types of packaging (snack bags, coffee bags, freezer bags, etc.).

The hinge and locking mechanism are fully integrated into the print, so there’s no assembly. Geometry is tuned for consistent clamping force and better sealing performance.

This version includes small built-in mini supports in the most vulnerable areas – they’re easy to peel off after printing and help protect the hinge and latch during the print.

🖨️ Printing orientation & tips

Print flat on the bed as modeled (clip opened in the slicer view, hinge lying horizontally).

Keep slicer supports OFF – only the built-in mini supports should be present.

Avoid brims if possible; if your printer needs help with adhesion, use a narrow outer-only brim and be ready to clean up the edges afterwards.

Adhesion: PEI smooth or textured sheet with glue stick or another adhesion aid recommended.

🛠️ Recommended settings

Generic slicer profiles work well; treat it like a standard mechanical print:

Layer height: 0.20 mm (0.16 mm if you want crisper hinge details)

Walls / perimeters: 3–4

Infill: 20–30% (Gyroid / Grid)

Top/Bottom layers: 4–5

Material: PLA, PETG, ABS/ASA – all are compatible; PETG/ABS/ASA are better for heavy use and outdoor environments

Supports: Disabled (only built-in mini supports in the model)

📝 Notes

Print-in-place: after printing and cooling, gently flex the arms to free the hinge.

Carefully peel away the built-in mini supports from hinge/latch areas—don’t twist too hard to avoid stressing the joint.

Designed for indoor and outdoor use; for prolonged sun/heat exposure, prefer PETG/ASA over PLA.

🔧 Assembly & use

No assembly required – it prints as a single piece.

After removing the mini supports and freeing the hinge:

Open the clip, place it over the folded bag edge.

Close until the jaws fully engage.

Squeeze lightly so the hinge and latch “seat” properly on the first use.
