9 inches long by 2.56 inches wide (outside dimensions) Trading Card Box intended to store a small collection of trading cards that have been sleeved in KMC Hypermat penny sleeves with a small amount of clearance on either side of the card.
to minimize/prevent the corners of the print from lifting away from the build plate, I recommend the use of a 5 [mm] brim. Sharp corners are much more efficient at transferring heat away from a print than flat surfaces. Applying a small brim will increase the surface area of the perimeter of the print, which will help counteract some of the contracting forces as the corners of the box cool.
The interface between the top and bottom halves of the box requires some finishing/sanding post print, since once assembled, the box is very difficult to open due to minimal assembly clearance. Additionally, due to the layer lines from the two halves being in the same orientation, a card box that has not been sanded post printing will be nearly impossible to open.
I suggest sanding with progressively finer sandpapers, starting with 100 grit, working down to about 220 grit and paper. This will knock down the rough unfinished print surface, while slightly increasing assembly clearance. For a smoother finish, the print may be wet-sanded with the 220 grit (or finer) sandpaper. It is also recommended that a dust mask is worn during this process to prevent inhaling plastic dust created through sanding.
