I needed bookends for my shelves. After digging around I didn't find anything that suits my needs just right.
However I found this awesome model of "The Thinker": http://www.semaker.com/productdetail/11610
So I grabbed the "Lowest_poly_thinker_easier_to_print" model and started to modify it and here is what I came up with.
For my printing I used 0.2 mm layer height and no infill. Still if you want to have some infill anything in between 5%-20% should work just fine.
