Garmin Zero Spacer

I made my own Arca Mount for my Garmin Xero from a 1" wide 1/8" thick Aluminum bar. I threaded a 1/4-20 hole and used a Camera mount thumb screw.
I found that the screw would bottom out before the Garmin was tight enough to stay in place. So I designed up a quick little spacer that fills in the extra space and also keeps the Garmin Aligned. I used a piece of 3M VHB to hold it to the bracket.
