Making frames with the Infinity Mirror & Shaker Box Generator

Difficulty: easy frame, medium electronics. Time: 30 minutes for the frame, 1-2 hours for a wired infinity mirror. Methods: laser cutting or 3D printing.

Two flat plates with matching openings and a spacer ring between them: that simple sandwich is the basis of two very different crowd-pleasers. Fill the gap with sequins or glitter and seal it with clear panels and you have a shaker. Put a mirror at the back, a one-way mirror at the front, and an LED strip inside the spacer and you have an infinity mirror, the endless tunnel of light that stops people mid-walk.

This generator produces all three parts perfectly matched in circle or square form, with the practical details included: a wire cutout in the spacer for the LED leads and an optional hanger hole for wall mounting.

What You'll Need

Laser: 3 mm laser-grade plywood or acrylic for the plates and spacer; for an infinity mirror add a mirror acrylic back, a clear front, and one-way mirror film
3D printing: any FDM printer and one spool of filament for the frame parts
An LED strip (60 LEDs/m or denser looks best) and a USB power lead for the infinity build
Clear acrylic discs and your fill (sequins, micro stars, beads) for the shaker build
3M adhesive tape (467/468 for acrylic) to bond layers cleanly without glue squeeze-out

Step 1 - Pick shape and size

Open the tool and choose Circle or Square, then set the overall Size (50-300 mm) and the Frame Width, which is the border between the opening and the outer edge. A wider frame hides the LED strip better on infinity mirrors; a narrow frame maximizes the window on shakers.

Step 2 - Add the practical features

Wire Cutout: enable it and set the Wire Cutout Width to pass your LED strip leads through the spacer ring. Skip it for shaker boxes.
Hanger Hole: enable it and size the Hanger Hole Size for the screw or nail you plan to hang on.
The spacer thickness comes from your material; stack two spacer rings if you want a deeper cavity for chunky shaker fill or more LED depth.

Step 3 - Export

Download SVG for the laser, or STL/3MF to print the frame parts. The SVG contains both plates and the spacer in one layout.

Choose Your Build Method

Infinity mirror build

Cut both plates and the spacer from plywood or acrylic. Also cut a solid back disc from mirror acrylic and a front disc from clear acrylic, sized to the opening or the full frame.
Apply one-way mirror film to the clear front disc (wet method, squeegee, patience).
Stick the LED strip around the inside face of the spacer ring, LEDs pointing inward, and route the leads through the wire cutout.
Stack the sandwich: back plate, mirror, spacer with LEDs, one-way front, front plate. Bond layers with 3M tape rather than glue near the optics.
Power it on before final closing. Adjust the mirror gap parallelism if the tunnel bends; the effect depends on the two mirrors being dead parallel.

For a shaker box, the build is the same stack minus electronics: clear disc, spacer, fill, clear disc, with the plates clamping everything together.

Make It Yours

Use an addressable LED strip (WS2812B) and a tiny controller for animated color chases down the tunnel.
Make a sequin shaker name sign: shaker box up front, a vinyl or engraved name on the clear face.
Square format with a wide frame makes a striking infinity coaster-sized desk toy.
Build a wedding shaker with gold stars and the couple's date engraved on the front plate.
Engrave a design on the front plate before assembly; backlit by the LEDs it glows at the rim.
Gift idea: snow shaker with white glitter and a tiny laser-cut tree silhouette inside the cavity.
Stack two spacers and double the LED rows for a deeper, brighter tunnel on large mirrors.
