Anyone have experience pushing the ceramic design guidelines a little... My wall thickness stands around 3-4mm; but the text / font embossing/engraving is between 1.5 - 3 mm. Overall height is 3" for the 44mag and 4" for the AK47. Also, anyone have a good link to explain density? Is it simply based on the bounding box? I uploaded one model that I thought would be a cheaper version with more engraving, and it turned out to be more expensive??? Thx.
