Stackable Snap-Fit Drawers

Açıklama

Simple stackable drawers that securely snap together. Each drawer locks into the one above it, with the lid snapping onto the topmost drawer to complete the stack. The locking mechanism consists of a small nub in each rail track and a matching catch on each drawer rail (see the attached photos).I printed these on a FlashForge AD5X using a 0.16 mm layer height. Since the AD5X has a 220 × 220 mm build plate, I had to print the drawers standing on end and rotated diagonally to make them fit. If you print them this way, orient the model so the rail beneath the drawer is printed directly against the build plate, not the rail backstop. In the photos, the rail backstop is at the front of the drawer. Printing the backstop against the build plate would leave the bottom rail suspended.These drawers were originally designed to hold a snug 4×9 array of the Mahjong tiles created by zxynine:https://www.thingiverse.com/thing:4967487I scaled those tiles to 16 mm thick to better match standard Mahjong tile dimensions, and these drawers are designed specifically for that tile thickness.The model was designed in Fusion 360, and I've included both the original Fusion 360 file and a STEP file to make remixing and customization as easy as possible.
