Outline Heart Locket Charm
Open-faced and softly sculpted, this locket charm combines a heart silhouette with an interior cutout for personalization. It’s designed as an original, in-house-generated model, ready to preview in GLB and print in STL for keychains or pendants. The commercial license lets makers sell their prints freely.
Instant download after checkout — GLB + STL. Yours to keep. Original Apex design.
Or save with a themed 3D pack — more models, one price. You own the files.
How to print it
From download to finished print: open your STL, drop it into your slicer, and print an Apex 3D model — settings, orientation and one-piece flexi tips.
Step-by-step: after you buy, where your files land, how to open your download link, and how to get your Canva / Notion / STL / sticker files onto your device.
