Galvo Laser Focal Stick (100% 3D printed)

Speed up your laser setup with this easy-to-use focal stick, designed for rapid and accurate focus adjustment on galvo lasers using standard lenses (like 110mm, 150mm, 200mm, or 300mm).

This 3D printed tool is designed to help you consistently find the correct focal distance without fumbling with rulers or guesswork. It’s perfect for makers who frequently change materials or work surface heights.

✅ Key Features:

• Fast and repeatable focal distance checks
• Entirely 3D printed 
• Lightweight and durable design
• Easy to print – no supports needed
• Can be customized for different focal lengths

I designed this to make my own setup process quicker and more consistent. If you regularly use a galvo laser, this will be a great addition to your workflow.

The Large profile can be adjusted between 418mm to 548mm.
The Medium stick profile can be adjusted between 228mm to 373mm
The Small stick can be adjusted between 143mm to 195mm. 

I recommend having 2 screws in each piece to keep it secure and ridgid. I personally used PETG for mine but PLA will work just fine. The model is designed to be adjusted to the bottom of the lens. You can also add the lens or focal distance in the slicer but I figured I would just engrave it with my fiber laser.
