Thank you again for the great suggestion! I took advantage of your advice and just ordered one from Amazon.
You also gave me pause about the environment - I had considered the hot, cold, wet, greasy and vapors, but I had forgotten how bad they vibrate!
I took some time this morning and adjusted my designs accordingly, I will post them in a bigger post about the project when I'm more ready. I'm still gathering the parts and improving my 3D printers environment to cut-out the drafts (as I'll need to print several parts for the project).
Thanks again John! I'll definitely give you proper mention in the credits!
