I did this as a commission, this is a 90 centimeters long baseball bat for those that want to dress up as something that needs a bat but don't have one themselves. With the right material and settings you could even use this for casual baseball playing.

The design parts have a hole in the middle to fit a metal rod for ease of assembly. Included is also a full version of the STL if you want to slice it or modify it as you wish.
