How to Make a Laser-Engraved Keychain (With a Ring That Hangs Straight)
To make a laser-engraved keychain, you engrave your design onto a small shape, cut the shape outline, and add a ring hole placed above the design centre of mass so it hangs level. Wood and acrylic are the popular materials because they cut fast and take a ring easily. The detail that beginners get wrong is the ring position: put it off-centre and the keychain hangs tilted.
Step by step
- 1
Design at keychain scale
Keychains are small (around 30 to 50 mm), so use bold shapes and thick lines. Fine detail disappears at this size and can snap.
- 2
Add the cut outline
Draw the shape you want to cut (a rounded rectangle, a circle, or the outline of the subject) around the engraved art.
- 3
Place the ring hole for balance
Put the hole at the top, centred over the design mass so the piece hangs straight. Make it about 4 to 5 mm so a split ring fits.
- 4
Engrave then cut
Run the engrave layer first, then the cut layer, so the piece stays held in the material while the detail is burned.
- 5
Pick a durable material
Wood and 3 mm acrylic are tough enough for a pocket. Thin material snaps; too-thin necks around the ring hole break first.
Why the ring hole placement matters so much
A keychain hangs from its ring, so the hole is the pivot point. If the hole sits above the balance point of the design (its centre of mass), the piece hangs straight and looks intentional. If it sits over an ear, a corner, or one side, the keychain tilts and looks like a mistake. For an off-centre design, the hole should still sit above the overall mass, not the tallest peak. Good outline tools place the ring at the balanced point automatically and add a small connecting stem when the top of the design is uneven.
Engrave layer and cut layer
A keychain is two jobs in one file: an engrave layer (the art burned onto the surface) and a cut layer (the outline plus the ring hole cut all the way through). Order matters, engrave first while the blank is still held firmly in the surrounding material, then cut it free last. If you cut first, the loose piece can shift and ruin the engraving. In LightBurn and similar software you set the engrave layer to run before the cut layer.
Sizing and the fragile neck
Keychains live in pockets and take abuse, so the material around the ring hole is the weak point. Keep the ring hole a few millimetres in from the edge so there is a solid band of material around it, not a thin neck that snaps. At small sizes, bold shapes survive and hairline detail does not, so simplify. Around 3 mm wood or acrylic is a good balance of light and durable.
Wood vs acrylic keychains
Wood keychains have a warm, natural look and engrave dark-on-light; plywood is cheap and cuts fast. Acrylic keychains can be clear, coloured, or edge-lit and engrave to a frosted mark; cast acrylic gives the cleanest cut edge. Both are pocket-durable at 3 mm. Acrylic shows fingerprints; wood shows wear, pick based on the look you want.
From a photo or logo to a keychain outline
If you are turning a pet photo, a logo, or a piece of art into a keychain, you need a clean cut outline around the subject plus the ring. An outline tool can trace the subject, add the balanced ring hole, and export the cut file, so you go from image to a ready-to-cut keychain without drawing the outline by hand.

Make a keychain outline with a ringFrequently asked questions
Where should the ring hole go on a keychain?
At the top, centred over the design centre of mass so the piece hangs level. For an off-centre design, place it above the overall mass, not the tallest point, or the keychain will tilt.
Should I engrave or cut first?
Engrave first, then cut. Running the engrave while the blank is still held in the surrounding material keeps it from shifting; cutting it free last preserves the detail.
What material is best for a keychain?
Wood or 3 mm acrylic. Both are durable enough for a pocket. Keep the ring hole a few mm from the edge so there is a solid band of material around it, thin necks snap.
How do I make a keychain from a photo?
Trace a clean cut outline around the subject, add a balanced ring hole, and export the cut file. An outline maker does this automatically, including placing the ring so it hangs straight.
