My first Thing!

I gave these all unique names to help you find the STL easier.

If you are concerned about airflow, print one out and test it and let me know how it goes! I dont have a way of measuring airflow accurately. They have not seemed to affect my print quality as far as I can tell.

Make sure your support settings are tuned in to allow easy removal. Print slow for best results. I printed mine at 25 mm/s.
