When you install a spring shock absorber, the spring can hit the wheel shell on back travel. Install these dampers to prevent it. They are installed between the pedal hangers and suspension slider.
A little demo: https://t.me/eleclub_kingsong_s18/210633
No EUC disassembly required.
There are two models, for both versions of the EUC.
v2 model should also fit v1, but I don't own v1 for now, so it's not tested.
Tell me if you need any changes.
Print using flexible material. I use Bestfilament BFlex.
Use small infill and thin walls to make it softer. For my v2 I used single wall with 0.6 nozzle, 10% cubic infill, 3 top and bottom walls. It works flawlessly with my filament - zero noise on suspension back travel.
NOTE: It fits good on my S18, but may not fit yours. Some scale adjustment in slicer may be required.
I believe that it's due to the difference between each S18 instance. It may also depend on your printer's extrusion parameters.
Put it over the heads of axle clamp bolts. It should fit tight enough to not fall off by itself.
Put it inside the pedal hangers from above, narrow part down.
Use some sharp object to pry the dampers off.
