Green Lantern Dice Tower (repaired)

I was having a lot of trouble printing the original tower.
I repaired the file and removed the build in supports.
I separated the parts so that they can be printed independently if needed.
Support structures are recommended.

UPDATE:
Added some support structures with mesh mixer. These need to be tested and adjusted.
Feed back appreciated.

UPDATE:
Additional supports are needed. Auto generated supports fill the inside as well. More work on the support version is needed.
