LightObject laser cutter nozzle improvement
Description
This is a nozzle that can be swapped out with the default nozzle on a LightObject Air Assist Head. Instead of the barb for holding an air tube, this nozzle holds a 50x15mm fan to keep smoke and debris from drifting back up during use and dirtying the lens. It also holds two line-style lasers to create a crosshair for targeting where the laser will go without having to test-fire the K40 laser. Needed materials: * [LightObject head](https://www.lightobject.com/Mount-Fixtures/20mm-18mm-15mm-Laser-Head-wAir-Assist-Ideal-for-K40-Machine) * [50x15mm Fan](https://www.amazon.com/gp/product/B079BPS9Q8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) * [Line-style laser diodes](https://www.amazon.com/gp/product/B01N48M1VR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) You'll need to wire these up to the built-in power supply of the K40, but it's a pretty straightforward setup and works well. I have mine hooked up to switches on the control panel for ease of use (shown in the pictures), so they are only on when I want them to be. There is a bit of ugliness on the opening that holds the fan, but this was a print that didn't use supports to hold that area up, so keep that in mind when printing.
