More of a remake than a remix.
Started from scratch in F360 the top portion of tower on original with the lines, just wouldn't print, said manifold errors, overal the model printed fine.

I made the lines a bit thicker and changed up a few things, I am currently printing this now for testing. I am running .2 layer 4 walls and I was going to reduce but left top and bottom at 5, running 10% lines infil.

I created some slopes to help the overhangs, running no support, in preview it looks as if it should be fine, about 7 hours from now I'll know!

Also going to make it a pen holder!!!

Thanks for looking.
