Awesome 3D-printable pop socket. Print in place with no supports. Rafts optional but I didn't use them. I did use Magigoo to ensure adhesion to my glass print surface though. Print with 90% infill to make sure the screw doesn't break. Either PLA and PETG should work fine since that's what I used. The hardest part about the print is assembly. I recommend attempting to screw the pop socket onto the base before doing anything else to the print. Initially, the individual pieces will be slightly frozen together, which will allow you to screw them together without them spinning separately. Then you can gently wiggle the pieces so they separate and telescope out. It might take several times opening and closing to get the pieces to slide well, but I left the tolerances tight to make sure it would still work after the tolerances loosen with age. Finally, apply some good double sided tape to the base to stick to your phone. I just bought whatever they had at Lowes. Comment if you love soccer as much as I do!

Update 12/14/18: I made some minor changes to the models that should help the retention flanges not wear out as fast from repeated opening and closing of the pop socket.

Update 12/21/18: I just uploaded an updated file called "Pop Socket Round." It is definitely the best one, but it has to be printed at 0.1 mm layer heights.

Update 1/28/19: I just uploaded a file called "Pop Socket Round Blank Tall." It is a little better fit for larger hands and is less likely to collapse when using it to prop up your phone on a table. It's also the one I prefer to go with my Pixel phone case. The files labelled "short" are lower profile by 1mm when collapsed.
