Motivational Plaque

Check out the new project: https://www.thingiverse.com/thing:3636109

This is a poster thing or a plaque (depending on which way you look at it) and it says, ''If at first you don't succeed, destroy all the evidence that suggests you ever tried!''
I put 3 holes in one for hanging or pinning it to the wall and the other has no holes.
Dimensions are 184 x 117 x 3 mm
Awesome, am I right!? I designed this on Tinkercad and i would like to make this Customizable but I don't know how to so any advice on this topic would be much appreciated.
Thanks, and enjoy!
