Low-Poly Outline Monogram Initial I
Printed as a single piece with no assembly needed, this keychain comes off the bed with a clean, low-poly outline of the letter I. An original, in-house-generated design—no third-party IP—it includes a GLB file for 3D previewing and an STL for printing, with a commercial license.
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.
