A friend has an October birthday and is into spooky things and books. This worked out perfectly 👍🏻

I glued some flickering LED tea lights in the base (the smaller version is the default 100% model from makerworld) and the smaller version fit like a glove with some glue (shown in 3rd pic)

The larger version (150%) had a perfect ridge to glue a tea light to.

I then designed a 3D printed gift card since Amazon books mainly offers digital versions of their gift cards.
