Dual laser K40 air assist M3 stock head

thingiverse

I added two friction-fit holders at a 90-degree angle to accommodate a pair of line lasers to a standard air-assist design. The design is mirrored to position the M3 screw (or M4, which I used) behind the laser head at 12 o'clock and the air-assist nozzle at 3 o'clock. This arrangement places the two laser lines at 4:30 and 7:30, clearing the beam path and providing space in front for alignment checks. This custom design is tailored to fit standard line lasers commonly found on eBay. On my own aluminum laser head plate, I had to remove about 1mm from the left front corner to ensure clearance. However, this might have been a necessity due to the specific positioning of my plate rather than an issue with the design itself.
