Basically, some cobblestone repeaters that make a tower. It takes a while for them to construct it, so if you have any tips for me that would speed up the process, please leave them in the comments.

Additional Notes

I got the cobblestone repeater idea/plan from one of Drili's videos on youtube while i was looking for a video on how to make one. Great video, you should check it out.
