My car's electronics emits energy inside the cabin that is in the same band as laser radar detection. This blinder shields the forward laser sensor against the in-cabin emissions so you can still keep the laser band enabled.
I strongly recommend printing this in ABS or ASA because the heat exposure is quite high. There is a version with ears on it that will help with bed adhesion if other methods like rafts don't work well enough. Just trim them off after the print is complete.
