Phone lens scratch protector

After using my Asus ZenFone 2 (ZE551ML / Z00_AD) quite a lot, the case was finally used up. This did not only mean, that it does not fit into my custom designed cup holder adaptor anymore – I was fed up using one at all.

First step was to put some leather around my real keys as well as my 6-In-1 “Utili-Key”, but some scratches still appeared on the camera lens.


But not only the lens was getting scretches. Something had to protect either the lens, or the screen (or both). I choose to try somehting on the lens with OpenSCAD and the Sumpod:

//* Globals *

//* Functions and Modules *

module cyl_at_rot (h, r, t_x, t_y, t_z, r_x, r_y, r_z )
translate ([t_x, t_y, t_z]){
rotate ([r_x, r_y, r_z]){
cylinder(h,r,r,center=false); }}

//* Begin Code *
cyl_at_rot (.25,15/2);
cyl_at_rot (1.25,12/2,0,0,-.1);
cyl_at_rot (2,12/2,0,0,-.5);


…and it still works after five months!

The ring was almost too small to print, but I got it decently somehow and the Pattex Repair Glue Liquid from Lidl still holds it in place!

The glue is excellent anyway: transparent, gap filling, flexible, odourless, easy to use (much easier than J-B Weld at least 😉 ) – but only available sometimes at that discounter. Get some, if you stumble over it. It might even fix the sole to your shoe again.

Printed with the excellent EPR InnoPET from Innofil3D BTW. More on that later.
