Rotating Display table: changing the bottom + 18650

Hi!
I was faced with the fact that I wanted to use other components - buttons, switches, etc.

So I redid the bottom part. I made a completely solid part - for those who want to drill the necessary holes for their components after printing.
Additionally, I made lightweight versions, with holes, to consume less plastic and print time.

I myself printed the version - Base_perf.stl

I had the board for a long time - lgt8f328p, and I decided to use it in the project.
Arduino nano will also work! There is no need to change anything in the sketch!
