The laser alignment guide includes a housing having at least one sidewall and a base defining an interior volume therein. A cap is removably securable to an upper end of the housing. The cap further includes at least one light source that can emit a visible laser disposed thereon. A mounting bracket that can magnetically secure to a surface is disposed on a second end of the housing. In some embodiments, at least one light source is disposed on a sidewall of the housing. ## Claims ### Claim 1 A laser alignment guide, comprising: a housing having at least one sidewall and a base defining an interior volume therein; a cap removably securable to an upper end of the housing; at least one light source configured to emit a visible laser disposed on the cap; a mounting bracket configured to removably secure to a surface disposed on a second end of the housing; wherein the mounting bracket is configured to removably secure to the surface via magnetic attraction; an activation switch disposed on the cap wherein the activation switch is in electrical communication with a power source and the light source, wherein the activation switch comprises a dial configured to vary the intensity of the laser emitted from the light source. ### Claim 2 (depends on 1) The laser alignment guide of claim 1, further comprising an etching tool having a blade configured to score the surface. ### Claim 3 (depends on 2) The laser alignment guide of claim 2, further comprising a blade sharpener configured to sharpen the blade of the etching tool. ### Claim 4 (depends on 3) The laser alignment guide of claim 3, wherein the interior volume is configured to store the etching tool and the blade sharpener. ### Claim 5 (depends on 1) The laser alignment guide of claim 1, further comprising a horizontal bubble level disposed on the sidewall of the housing. ### Claim 6 (depends on 1) The laser alignment guide of claim 1, further comprising a vertical bubble level disposed on the sidewall of the housing. ### Claim 7 (depends on 1) The laser alignment guide of claim 1, further comprising a vertical bubble level disposed on the cap. ### Claim 8 (depends on 1) The laser alignment guide of claim 1, wherein the power source comprises a battery disposed within the interior volume of the housing. ### Claim 9 (depends on 1) The laser alignment guide of claim 1, further comprising a measuring tool configured to fit within the interior volume. ### Claim 10 (depends on 9) The laser alignment guide of claim 9, wherein the measuring tool is telescopic. ### Claim 11 (depends on 1) The laser alignment guide of claim 1, wherein at least one light source is disposed on a sidewall of the housing. ### Claim 12 (depends on 11) The laser alignment guide of claim 11, wherein the light sources are disposed such that the light sources emit a laser in three directions, defining independent axes of a three-dimensional graph. ### Claim 13 (depends on 12) The laser alignment guide of claim 12, wherein the laser is directed through the various light sources by a reflective assembly that is configured to selectively reflect the lasers via rotation of the cap. ### Claim 14 A laser alignment guide, comprising: a housing having at least one sidewall and a base defining an interior volume therein; a cap removably securable to an upper end of the housing; at least one light source configured to emit a visible laser disposed on the cap, wherein at least one light source is additionally disposed on a sidewall of the housing; the light sources are disposed such that the light sources emit a laser in three directions, defining independent axes of a three-dimensional graph, wherein the laser is directed through the various light sources by a reflective assembly that is configured to selectively reflect the lasers via rotation of the cap; a mounting bracket configured to removably secure to a surface disposed on a second end of the housing; wherein the mounting bracket is configured to removably secure to the surface via magnetic attraction; an activation switch disposed on the cap wherein the activation switch is in electrical communication with a power source and the light source, wherein the activation switch comprises a dial configured to vary the intensity of the laser emitted from the light source.
