Yokoso Rainbow Tower - mini version... N-scale (sort of)

I saw a picture of the Yokoso Rainbow Tower and thought.. I'd like a simplified version on my Japanese N-scale layout.

The aim is to print the internal sections with translucent blue and put a couple of LEDs inside.

Edit 30/11/2023

On printing , I found internal parts were a fraction too wide.

These have now been updated..

Edit 7/1.2024

Added a bas with steps and a front wall

Missed one of the internal pieces.. Fixed now
