"A brand new gear, every year."
I have changed the first (small) gear 4-5 years ago and then the second (large) one 2-3 years ago.
Now the third one went wrong so i continued the previous practice.
I have made this 3D model by measuring the original, but broken gear.
To create gearset, I have used this gear generator: https://evolventdesign.com/pages/spur-gear-generator
To make a spatial model from 2D dxf or svg, you can use FreeCAD: https://www.freecad.org/
You can find here the 1st gear design I have used previously: https://www.thingiverse.com/thing:949801
Here you can find the 2nd gear: https://www.thingiverse.com/thing:6043354
I used this printed gear for 2.5 years in my W126. I have just found some green, sticky residue on the surface of the gear while disassembled the odometer because of the defective 2nd gear. Maybe it caused by the reaction between the lubrication and the resin.
Parameters:
D = 25 mm
Z = 48 teeth
d = 7 mm
z = 16 teeth
