Shelf bracket World of Tanks w/o screws

I made this for some acrylic shelves I have on hand. They have a width of 60mm. Since this is for the 3D-printed tank models of World of Tanks, I chose the logo.
There will not be much weight on it, so I will stick them with Tesa Powerstrips to our cabinet.
Don't want to put screws in.

I added a left and right version to make it look fabulous from both sides ;)
I added also a version for 100mm width.

This thing was made with Tinkercad.
