KIA ceed road sign recognition disabler

I have KIA ceed 2025. I like speed limit sign (bottom position) being displayed (with warnings turned off), but I hate the warning sign (top position) being very often false-positive. AFAIK the top sign can't be hidden by SW setting, so I created HW gadget to hide it out.

I recommend you to print it from filament rated for 100C or more, matt black. I tried Prusament ASA Galaxy Black (not perfect thermal resistance, but good color) and Prusament PC Blend Urban Grey (perfect thermal resistance, not good color). In the future I'm planning to try PC-CF.

Curently I have 2 versions. Both are very easy to install and uninstall, without damaging the instrument cluster of your car (in contrary to the sticky tape).

v1.7 (easier to print, good fit in the car)

• only 3 grams of filament
• quick print
• PC requires gluestick (on satin bed plate) and 0% infill
• no post processing
• for tall or short drivers it can block road sign incorrectly as it hovers around 5 mm above the display

v2.2 (requires supports, perfect fit in the car)

• around 5 grams of filament
• slower print
• better result
• didn't try PC
• slight post processing (small ultra flush wire cutters may be needed)
• fits perfectly regardless of driver's hight (sits flush with display)

Get inspiration by my setup in 3mf files, but feel free to experiment with your printer settings.

Note: There are 4 prototypes in the photos:

• v1.7 grey PC
• v1.7 galaxy black ASA
• v2.1 green PLA (not perfect fit yet, but easier to see on photo)
• v2.2 galaxy black ASA (my favourite)
