Stormtrooper lightsaber

This is only a test and WIP. I do not own a 3D printer yet so don't know how this will come out. I'm also very new at 3D modeling so constructive cristism wil be appreciated.

I saw this on pictures on the net and wanted to try to make my own. This is heavily inspired by others but I did the model myself.
I don't know about if the scale is correct but i suspect the diameter of the handle should be around 40mm. This should make the model about 300mm long.
Havn't gotten around to slicing or what ever terms are used when 3D printing. But if anyone wants to remix it or try printing it be my guest. Just don't make any money on it.
