If you print with PLA, I recommend that you print with a 25% or higher infill to prevent the sticks from breaking quickly. 

When designing, I wanted the rods to be thin, but after printing, I turned to a more cylindrical design because it did not inspire confidence. I will use it like this until my sticks break. Then I can prepare a new version and share a photo of it.

I am waiting for your comments and rating. I hope it will be useful for you.
