Laser Focusing Knob
thingiverse
This extension focusing knob is designed for laser diodes used in many small laser cutters and engravers, allowing you to precisely focus the laser with ease while protecting your fingers from the high-power beam emitted. You can create this knob using either 3D printing or laser cutting technology. The diameter of my original laser knob was 16mm, so I designed this extension knob with an inner diameter of 16.5mm to accommodate my specific tolerances. If you have different tolerances or a larger/smaller knob on the diode, feel free to adjust the scale accordingly. I also uploaded a modified SVG file for anyone who only has access to a laser cutter and wants to cut out this extension from plywood or acrylic material.
With this file you will be able to print Laser Focusing Knob with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Laser Focusing Knob.
