Twisted (Modular) Mad wizard tower

in memories of an old 80's cartoon i build a modular wizard tower, the spiral stairs can be mounted on both side and can rise clockwise and anticlockwise, also there are more kind of tower floor and inside.
the upper floors could have loopholes or little (gothic arched)windows or both side door to switch the spiral stairs.

here is the lower part, compatible with Openlock and openforge basement so you can stick it and use it on your campaign.

*EDIT 29/05/2020:*

Ok i upload the modified and easy to print base tower.
Hope someone will print it and send a photo of it, any feedback is welcomed.
To print it you need this pieces:
1x - Torre-semplice-antioraria
4x - piattaforma-scaletta-antioraria
1x - piattaforma-alla-porta-antioraria
1x - piattaforma-lato-porta-antioraria
1x - pavimento-piani-superiori

the floor is new, i like it more than the past one, so ...
again, if someone print it, please send a photo or feedback to improve the desing.
thanks and happy printing!
