Brick style lightsaber - Extendable

I made a lightsaber handle for BIC pens based on a famous plastic brick company's lightsaber handles, and decided to experiment/practice my CAD skills with an extendable blade. After a couple iterations I'm happy with the function and durability. I even added a little hole to turn it into a keychain if you wanted to!To assemble the bottom cap slots into the base after the blade is inserted. It fits tightly, but glue is recommended if you want a permanent fit. I did try to print this with silk PLA and found that it it delaminated too easily and broke.
