Book Spacer

This is admittedly a very niche tool, but I like to have my books nice and even on my bookshelves, so I created this to make sure everything's nicely lined up. You can stick the books on the shelves close to the edge, then run this along to get them pushed back to an even 1 1/4".

The model is in two parts, handle and "blade", because I wanted to avoid supports (and experiment with designing to use bolts in a print).
