Printing a wavy surface causing rings, any way to flatten?

[Rob_B]

I have an .stl of a tactile map I'd like to print however it includes a section of water, this is given an undulating surface from the source that generated it and when printing it looks like below. Is there any way to flatten these areas?

Good shout, I could potentially add it as negative to cut off the top layer, however it's a very fiddly outline on the print so with no draw tool it may end up a combination of lots of random shapes to fit :/

just to flatten that out, so no dips or bumps.
I've got some way by using a load of negative parts of varying shapes, its just time consuming

I'm currently playing with a 3mf

Aah, it's somethin I created so only have it locally

'created' is doing a lot of work in my sentence

In case anyone else uses touchmapper and wants to remove an object/water/the location cone.

Go to objects, split into parts, the 1st one will likely be the cone and from there just navigate through the objects until the one you want to delete is highlighted
