Due to the nature of 3D FDM printing this item may contain tiny visual blemishes and may require some trimming and detail painting for optimal visual appeal/fit. Similar to what you would expect to do with model parts. These blemishes in no way affect the functionality of the part. 3D printed items are susceptible to heat and may warp if left in direct sunlight. This can easily be corrected with a hair dryer or light heat gun use. Care should be taken to not leave in hot cars or direct sunlight. A coat of paint will help with this.
