A trash can bin for your car that's soft and flexible if you print it with ordinary PLA!
This is make sure you don't hurt your self getting in and out of the car and it's light weight with rounded corners - meaning if you have an accident it's most likely not to hurt you or your passengers.
You can either attach it directly with velcro or double sided tape but i recommend you print and use the fastners.
Attach the hook to the trash bin as seen in the pictures and the holder to any surfare - you can then easily remove and empty the bin.
