SIX WAYS TO BUILD IT

Each structure defines how the light comes through and how the piece is assembled. Every dimension adjusts to your printer and your acrylic.

SOLID FACE

wall 2.0 / face 2.0

The classic: the face diffuses the internal LED light.

LIGHT DOTS

dots 4.0 @ 8.0

Perforated face following the letter outline. Marquee effect.

FLUSH ACRYLIC

clearance 0.20

The acrylic sits flush with the face. Premium finish.

INSET ACRYLIC

lip 2.0 / ledge 2.0

Inserted from inside or mid-wall, for even light.

BACK-LIT HALO

rear acrylic

Opaque face, light spills onto the wall. The floating effect.

BACKING PLATE

margin 10

A single sheet with the full silhouette of the logo, behind the design. For line-art and complex marks.
