Hi Emmanuel -

There are two bad objects in this file. Use SelBadObjects to find those, and ExtractBadSrf to extract the bad surfaces in those objects.

Apart from that, there are gaps between good surfaces as well:

Additionally, there are lots of very small edges / gaps between edges:

Overall, I’m afraid this is going to need quite a bit of fixing before you should even attempt to offset the objects.

If you’re only interested in a quick model to 3D print, you could try the ShrinkWrap feature in Rhino 8.
