The lightsabers are in tomorrow land.
The light sabers are in Adventureland in the store over there. Sorry, I didn't see anything else that you can make yourself except at the Lego store in Downtown Disney.
There is a boutique for girls who want to become princess.
They also have wooden and metal model kits you can build there. They are small though. The size of your fist. Also lego kits
There's a racecar/RC car place in Downton Disney and a Build-A-Bear too.
