Looks to be made from PETG filament. I would make them for cost for folks here plus shipping. Shipping actually would be more than the price of plastic + electricity.Hey Dave - I think it's intended for one car, but with the idea that some blend doors might have different holes than others, so there would be "extra" plugs.
I don't remember how long Brian said they took to make a full kit - maybe 2-3 hours? He said his costs were something like $1.50-2 for the plastic and he was initially selling them for $39, until he kept lowering them down to $9.99 to try and screw over the Chinese copycats.
