Maybe others will have better luck with this one. It's a bookend with a quote from H.G. Well's The Time Machine:
“You know that great pause that comes upon things before the dusk, even the breeze stops in the trees. To me there is always an air of expectation about that evening stillness.”
― H.G. Wells , The Time Machine
I was designing a little time machine to go on it as well but after many tries in the resin printer nothing happened. The embossing around the edge are shapes representing a time travel process where a phantom universe moves into another universe using a wormhole temporarily connecting the two realities... I thought it was fitting despite the differences in methodology.

Tried adding the time machine I made a few years ago to the book end. Started by printing it separately. Unfortunately the connection to the machine and the disk is small, delicate. I was thinking of redesigning it to make it free floating sphere attachment that can rotate, but because of how small it is, it has only survived printing once, and later fell off when we dropped the print. The other issue is the control panel. The attachment to the machine was so delicate that it was unable to make it through. Making me wonder if I should consider making it a separate print that attaches to the main body. Another part of me wanted to see how it went if I combined it with the main bookend. But after months of working on this with zero success, I took a break. When I got back to it I found out someone else created an all around better time machine. Unfortunately we had to move and we haven't set up the resin printer yet, so I've been unable to attempt printing theirs. My hope is that it's an easier print than the monster I created. I will update once we try again.
