Laser Line Fixture
My 3D printed laser line fixture was designed to provide the garment decorator with a cost effective alternative to similar devices in the marketplace. It is self contained and mounts to a standard 1/4″-20 stud found on most light stands and tripods. The fixture includes 4 line lasers, 4 laser holders, a 7″ Aluminum rod, and a mounting tower with a battery pack or optional power transformer.
The price of the laser alignment fixture is $145.00 with the battery pack or $155.00 with the plug-in transformer and includes shipping to anywhere in the continental USA. Use the safe and secure Contact Form to place your order.
Note: it does not include batteries or a light stand.
A major challenge that I had to overcome was the amount of play in the lens of the laser. The red focus knob solved the problem by nesting it in a slightly tapered cavity built into the laser holder. After the laser is focused, the line is positioned and then the laser tube is pulled back so that the focus knob is seated in the cavity before the screw is tightened. This action removes any play inherent in the laser lens.
I have noticed that some of the lasers are not perfectly coaxial with their tubes. What this means is that the laser may not point exactly where the tube of the laser is pointing. There is nothing I can do to fix this problem but it shouldn’t be much of an issue due to the flexibility built into the fixture. The individual lasers can be re-positioned on the rod and slid closer or more distant from each other in order to achieve a desired placement. Sometimes the laser tube can be turned 180 degrees in it’s holder resulting in the same line position but offset in the opposite direction.
I will describe how these lasers are constructed in case you want to swap holders and then I will provide a YouTube video on how to focus and align everything correctly. Of course you can always use the safe and secure Contact Form to get in touch with me for additional support.
If you want to move the laser tube to a different holder, you need to remove the lens and slide the tube out the back side of the holder because all the wires are attached to each other. Be advised that the lens is spring loaded in the tube so be careful when you unscrew the lens. Usually the lens will disassemble as shown but sometimes the black (or brass) threaded bushing remains in the tube and the lens falls out.
If the black (or brass) threaded bushing unscrews from the focus knob, it will look like this. It needs to be reassembled by dropping the lens in first with the smooth side down, then screw in the threaded piece with the slotted side against the lens.
This is the stacking order of the laser focus knob, lens, and black threaded bushing. Drop the lens in first, ribbed side up, next the bushing slotted side down and tighten securely with your fingers. Reassemble in the tube by placing the spring inside and screw the lens assembly to it. You are now ready to re-focus the line.
