The D12 dice kept failing and the cogs would be left attached to the supports (resin printer) so I put it in 3dbuilder and recessed them a little.They seem to print ok now, only the 6 or 9 cog stuck this time but on the other prints as long as I was careful removing them it was fine also had to resize in slicer to 18.55mm to match the full set.
