Trading Card Box - Version B

grabcad

At 9 inches long, by 2.56 inches wide (outside dimensions), both boxes are intended to store a small collection of trading cards that have been sleeved in KMC Hypermat penny sleeves, without much side-to-side movement. The interfacing surfaces were drawn with .0005 [in] clearance per surface, which will essentially be an interference fit if the prints are not reworked post printing. Wall thickness for non-mating surfaces has been set to .125 [in], and .0625 [in] for mating surfaces. This provides relatively flexible walls in the middle of the box, while the short ends remain rigid. with a combination of tightly dimensioned assembly surfaces and the rigidity of either end of the box, it is very difficult for the box to come apart without manually separating the two halves from one another.The interface between the top and bottom halves of the box requires some finishing/sanding post print, as 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 disassemble. I suggest sanding with progressively finer sandpapers, starting with 100 grit, working down to about 220 grit sand 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.For more information, check out my build log at: ianpchase.com/projects-blog/2019/2/24/inside-the-box
