This is a great design that I've dialed in and got working very well. Looks great and is very functional. This stand allows multiple viewing angles and best of all has a quick grab/release mechanism that grabs and locks the phone in when you let go and releases when you pick up the phone.
This design currently works best for larger phones (iPhone 8 plus/XS Max size), but I am working on a universal version, just need to get my hands on the smaller devises to test and dial it in.
The entire design is printable other than a small extension spring that needs to be installed when putting the stand together.
5mm x 10mm extension springs work great and can be found in this kit for a great price:
