Having something fancy for a single item, for that this shelf is the right thing. One could use it as a key holder, hold your wifi acccess point, or in my case, to hold the elixir of life, a pack of cofffee. The current design should be stable enough to hold up to 1kg permanently (checks with 1.5kg were less reassuring). For long term use, PETG better than PLA, since PLA gets brittle over time and might break under constant load.
