A Great design:sleek and very fast looking with a very strong dose of the Star wars "shape language". Could you show us how they come apart for DIY installs and give us the dimensions?
Here you go Johannes:

As you can see, the saber consists out of a main body, pommel and blade holder that screw together (NOT MHS compatible)
We don't sell these as empties, but you are welcome to purchase a stunt which you can easily upgrade. All pommels come vented for future sound installs.
Oh, and the ID of the hilt is an overall 29 mm with a 1" blade holder
