I love my Sunflower Clock by Romano Ruggeri but the PETG I used for the petals is quit flexible. Because of that they sagged quit a bit and the hour markers were not in their correct positions anymore making the time-reading overly inaccurate.

So I designed this simple stabilizing ring-brace that connects all of them simulatiously and takes the strain of their weights. Use it in addition the Romano's original clips.

In that way the petals sag much less and the hour markers hold their correct positions more accurately.

Optimally print in transparent PETG.
