I had an old magsafe wallet and decided to not let the magnets go to waste. I made this mount for my indoor trainer bike that I use in the winter. This should be compatible with most bikes out there as long as the stem is longer than 50mm or so. Holds to the bike with 3 zip ties
Assembly:
I printed this in PLA as it will just be indoors. If you plan to have this outside, I would choose PETG. The phone seems to hold well (I dropped the bike a couple times and it did not pop off), but I am not sure I would trust it on the road.
