Shelf wall hanger

I made this wall hanger for shelf with the depth of 135mm, but you can make it bigger if you want. It is designed so you can make several shelfs in sequence, like I did. 

Printed in PLA 4 years age, but would recommend the use of PETG or something stronger. 

Boost MeI think I made something unique, support me if you want.
And if that didnt work, here is a joke: Have you heard about the Disney virus?
It makes everything on your computer go Goofy.
