The file 'Quad Lock – Inspired Bicycle Smartphone Mount 3D Printer Model' is (step,stl) file type, size is 817.8KB.
It's a "Quad Lock" inspired bicycle smartphone holder. Or basically anything holder. I've been using it for past year or so and it worked flawlessly.
All the credit goes to the guys at quadlock (https://www.quadlockcase.com/)
and some of the geometry used is taken from and improved upon (in my opinion) https://www.thingiverse.com/thing:2590838
All of the parts printed from PETG apart from:
"QuadLock core" which was printed in PA12 Nylon for strength and
Phone "female adapter" printed in ABS because ABS whas the material of the phone case. (it was easier and stronger to acetone-weld those together rather than glueing)
In between the "lock" and "core extension" there are three springs (I used springs taken out of a cheap pen) - see the parts.jpg for details.
