Compounded: Geiger missing piece

I'm posting here in hopes for a response.  I reached out about a week ago through the contact page, but have not heard back.  

I kickstarted the Geiger Expansion, received it a while ago, but didn't try to do anything with it until just recently.  When I did open it I found that I am missing the plastic "rivet" to hold thespinner together.  How do I do about getting one of these?

Hi there.

I don't seem to have received your email in my inbox. If you can send one directly to contact@greaterthangames.com, rather than through the form, I'll get you all taken care of.
