This is a remix of the fine looking Gravity Falls water tower byJukka Seppänen https://www.thingiverse.com/thing:1369312

I have attempted to recreate in Tinkercad a wooden staved water tower similar to the Petticoat Junction TV series tank with and without railings.

My best estimate is that it the supplied stl files are 1:24 scale.The supplied files are 265% bigger than Jukka's Gravity Falls water tower.

The photos are a proof of concept as I only doubled the size of the Gravity Falls tank.

I have added a couple of pins to help line up the model when gluing. They may need to be sanded as the tolerances are less than 0.3mm.

I printed the upper base without supports but chickened out and used supports for the lower base. I suspect that a 10mm brim may be sufficient if your slicer can easily bridge the gap.

For those of the era, here are the accompaning lyrics to the theme song by Earl Scruggs
Come ride the little train that is rolling down the tracks to the junction.
Forget about your cares, it is time to relax at the junction.
Lotsa curves, you bet
Even more, when you get
To the junction
(Petticoat Junction)
There's a little hotel called the Shady Rest at the junction.
(Petticoat Junction)
It is run by Kate, come and be her guest at the junction.
(Petticoat Junction)
And that's Uncle Joe, he's a movin' kind of slow at the junction,
Petticoat Junction.
