It may be the conversion from the original CAD, but the model mesh isn’t clean. The holes where the top part slides into are messy and render bumpy and distorted. Also the diamonds are suppose to be in an indent, like in the renders. But the model just has them sitting into the top piece. Looking back I saw the raw model render had it not in a channel, but the beauty renders do show it. Perhaps those are not the CG render? I bought it based on the beauty render.
