Warning! The inner part won't fit smoothly without adjustment, and I'm still planning to sand it before finalizing the model. This remix combines three outstanding design concepts that I found online. The primary inspiration is at https://www.youmagine.com/designs/k40-chinese-lasercutter-air-assist-with-cross-lines-laser. I adore this design's elegance and innovative laser pointer feature, so I adapted it to incorporate two other exceptional ideas: 1) From http://www.thingiverse.com/thing:445354, where the designer merged two laser lines into a crosshairs beam that works across varying heights; 2) And from https://www.youtube.com/watch?v=CC9kGOlxlHs, I took the concept of adjusting focus and put it to good use. The design consists of three main parts. Part 1 is the principal head extension, replacing the original lens holder. The fit isn't quite there yet, but I'm optimistic about it turning out okay. Part 2 represents the inner slider mechanism for fine-tuning the lens height.

I'd appreciate your review and consideration to give due credit to its creator; they deserve recognition. Concerning the Bill of Materials (BOM), the laser modules are from http://www.aliexpress.com/item/Free-Shipping-Red-5mW-650nm-Line-Laser-Module-Focus-Adjustable-Laser-Head-5V-Industrial-Grad/32290741097.html.
