Removable laser base attachment for bubble levels

A laser base for a bubble level having a reference surface, said laser base comprising:

• (a) a body having a first end, a second end, a flat, longitudinal top surface extending between said ends, and a flat bottom surface parallel to said top surface;
• (b) a laser module mounted in said body that emits a laser beam parallel to said top surface upon application of power, said laser beam at a fixed and known distance from said bottom surface;
• (c) a power source providing said power for said laser module;
• (d) a switch for controlling application of said power source to said laser module;
• and
• (e) a securement for removably attaching said bubble level, said securement including a longitudinal T-shaped slot having said top surface as a floor and adapted to receive said bubble level such that said reference surface abuts said top surface, and a thumb screw extending adjacent to said slot to frictionally retain said bubble level in said slot.
