This is an updated shelf for the Omniwall panels that the remixed tabs like on my Updated Hanging Bin.
Similarly you can chain these shelves together by printing multiple.
There are a few different tabs to choose from. If you would prefer to have the nuts on the outside of the shelf, there are two models (mirrored) with a recess for them. If you would prefer the bolt head on the outside or to link a few together, there is a model with only a hole.
The author marked this model as their own original creation.
