Pyramid book stand

We put a shelf on the living room wall to display our books, but we needed a book stand to hold them tight in place.
I designed this little pyramid as ornament, so the stand wouldn't be boring.
I recommend better temperature control than mine at the tip, since it is way too smal it tends to melt (at least on ABS). Since I am still going to sand, prime and paint, I didn't care much about that issue.
The design is about 10cm tall, more than enough to support small books.
