Mount for a Nokia Lumia 520 mobile onto standard handlebars using two cable ties (just to keep it universal / easy!) The mount holds the phone using friction only, if your calibration is out you might need to wrap some rubber bands round the lower plastic part to hold your phone in. I withhold all responsibility for broken screens as a result of using my design, I will definitely design an update if I have any trouble!Print with 2 shells and 20-30% fill. No support is needed - if my $200 kit printer can do 50mm bridges, so should yours! Use a couple of cable ties to attach to your steed!
