Marble Outline Monogram Initial R
Sell this original keychain design in your shop — generated in-house, not stock or third-party IP. The included GLB lets customers preview the marble-textured “R” in 3D, while the STL keeps production simple. Your commercial license covers both digital sales and physical prints.
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.
