GorllaPod SLR Nexus 5 Dock

I wanted to build a dock adapter for my Nexus 5 that would clip into the standard receptacle of my existing GorillaPod SLR (the largest size).

Nexus 5 fits great, but the tab doesn't lock into place in the tripod. Fortunately, the friction on the side is enough. I suspect that may be a quality issue with my printer, the model measures out correctly. YMMV
