Small 2" x 8-1/2" Shelf

I needed a small shelf I could thumbtack to the wall so I drew this up in Tinkercad quickly. The first time around I made the walls 1/16" thick and it warped all up when printing, so the second time around I added in some more diagonal supports and made the walls 1/8" thick. This one takes a little more time to print, but turns out pretty decent.

The version in the picture was printed with some Zentoolworks Clear on a Davinci 1.0.
