Practical Book End Holder

A real 3D-printed bookend shouldn't be a perfect right angle —
it should be 87°.

• That tiny tilt helps books lean naturally and stay in place.
• At 87°, it prints clean — no supports needed.
• However, you can easily scale and print it to a even larger/smaller size!

It's super thin, but surprisingly tough.

• The thickest part is just 2 mm,and with two reinforcement ribs, it's almost impossible to bend.
• All the edges are rounded, so your books won't get nicked or scuffed.

It's a super practical design,
but on the outside, it looks plain — maybe even a little too simple.
I used to worry people wouldn't like something so ordinary.

But, 

my mom once told me,
“Even from an ordinary family, a big star can rise —
just like your favorite, Cristiano Ronaldo.”

And that hit me.
Those two ribs on the back?
They're like Ronaldo's mom and his fans —
quietly supporting him, making him stronger.
