I made this because I was tired of my Popsocket getting hung while putting my phone in my pocket. I wanted something that you could barely tell was there. I tried to make it thin enough to still let you grab the Popsocket properly. People with larger fingers may have issues using this. I used a spray adhesive from Home Depot to attach to the phone.

Updated V2 - This version has a smaller foot print and has a matching cap. V2 is designed to work with the V2 cap. The cap is lowered on the edges to meet the bevel ring to create a smoother transition and reduce the chance of catching on something. I printed the ring at 100% infill and used a file to create slight dimples in opposite sides to allow for grabbing the cap. As you can see from the photos, the smaller footprint allows for my new case with a kickstand. Credit to https://www.thingiverse.com/thing:2187235 as I used this cap and just modified the edges.
