This evening I sorted out the Sumo ring and associated ponds. Sadly with the ponds I had some issues around bulging and warping. I could reprint them, but to be honest I will sort out any issues with Greenstuff.
I evidently printed the roof pair with the orientation wrong. I also forgot to hollow them. I have a bulging the part facing each other. I have sanded them and used a file to reduce it a bit, but still have a bit of a gap. Once again I will use Greenstuff to fill the gap.
I also printed a trio of tanks for a colleague who is making a rather fabulous 3D map to play an invasion of Shetland game with his secondary pupils. These are to show the kids what they looked like.
