Universal car phone holder is an improved version of the excellent original design. This holder is now wider and includes two more arm sizes. Its design helps eliminate any ringing that might have been experienced with the previous design. This holder needs zero support for printing.
It comes with a trick to easily slide the arms in and out, using either ethyl alcohol or rubbing alcohol to wet the arm and slightly inside the arm hole. This should help with the friction. If the arm leaves the support, you can use a small flathead screwdriver to open the end so it doesn't leave the holder.
