Réunion puzzle - île de la Réunion

I printed the Corsica puzzle : https://www.thingiverse.com/thing:2793004 but a colleague wanted an other island.

I tried to follow the Make Anything tutorial : https://www.makeanything.design/3d-puzzles/ but adapted it to use only free applications.
In the tutorial, use the 3D Printer Tolerance Test to check the thickness you need.

I reworked the shape made by Terrain2STL and added the compass from iago_gc

I printed the 0.17 mm thickness version, but also made a 0.28 mm in the zip file.
