After 1.9 was introduced many item elevator designs were ruined and hence I have tried to design a good alternative to the pre existing models...

This Item Elevator is completely safe to use meaning you wont lose a single item while transporting them up which is always great!
The Redstone is all hidden beneath the ground so you can build this almost anywhere!

It does not use massive amounts of resources so give it a try! And besides Slime Blocks make everything better! Am I right? Haha

1.Download the file
2.Extract the Folder from the .zip file
3.Type %appdata% in your start menu search
4. Open the .minecraft folder and open 'saves' folder
5.Paste the folder into this folder
6.Open up Minecraft and you will find the world installed and ready

Download and have fun!
