This is a snowflake for a letter board. The arm which attachs to the board is 1.2mm wide by 9.7mm long, you could make it thicker if needed to fit your board.
I found the original Snowflake (that it was remixed from) had a hole in the middle so the arms all fell off as they were not attached (you can clearly see it when viewing the slices). I added a solid block into the centre and its now good.
Winter has arrived to my letterboard !
Infill at 25% saves a tiny bit of filament. No need for supports etc. Take care when removing from the bed, slowly bang each leg (they are pretty strong).
