While the Pred Gridginity boxes stack nicely, it is difficult to remove a box in the middle of the stack. This modular design allows for many configurations to suit your application giving easy access to any of your boxes. Print as many of the bases you may need for your boxes and top it off with a top plate. Dovetail keys lock the bases horizontally and the corner pins keep things aligned vertically. The “chisel” is used to clean up the dovetails after printing to make it easier to slide in the keys. The A1 was used to print this but of course any of the other Bambu printers, except the A1 Mini, can be used to print the models. PLA Basic was used for all the prints and most load is in the vertical direction.
