Hello municipality, I just got on it and made a magnet holder for the smartphone with local on-board equipment. I have not found a satisfactory alternative solution so far. I don’t want to drill anything in any way or clamp anything between what might leave behind after years of printing. Required material: – magnetic holder from the bay for 5€ – angle iron – countersunk screw (in my case a safety screw of a brake disc + nut M6 – 2 underlay disc en – Shrink tubing (can also be painted black, not visible area) – a new storage tray, also from the bay (15,90€ instead of just under 60€ at the friendly one) I think it looks semi elegant. I hope now that driving dynamic influences do not make sure that the shell jumps out. Can I unfortunately not test until tomorrow, then my new fatter will be approved. In any case it is residue-free retrofittable 🙂 I will report what the test drive has revealed tomorrow, then mac h i also still pictures with flanged mobile phone 😉
