This is a 25.4 mm (1-inch) blade plug that I designed for my Sentinel light saber remixed from Plugs with openscad by benengel. It is 50 mm (1.97") in height.

The design uses the Font Awesome library to display the Rebel logo and hence it will not work with the Thingiverse Customizer. Use some design software like OpenSCAD to customize/change the logo. You may need to install the Font Awesome font for your OS for the logos to work correctly in OpenSCAD.

If you are satisfied with the above-mentioned dimensions then print using the STL file.

The blade plug is mostly hollow throughout but to prevent dust from entering the lightsaber there are a couple of layers in between which cover the hollow tube completely but still allow the light to pass through. Suggest you print using the same color filament as your light saber LED to maximize the effect.
