Assembly Instructions

  1. 1

    Step 1: Lay out all wooden panels, 3D-printed blue parts, and hardware. Check that you have everything from the parts list.

  2. 2

    Step 2: Insert the left and right wall panels into the slots on the base plate. Make sure they're fully seated.

  3. 3

    Step 3: Position the back panel between the side walls and secure with M3x8mm screws, nuts, and washers through the corner holes.

  4. 4

    Step 4: Attach the axle mounts to the inside faces of the left and right walls using M3x10mm screws. The axle holes should line up.

  5. 5

    Step 5: Use the four corner brackets to mount the hopper bottom plate horizontally between the walls, about 2/3 up from the base.

  6. 6

    Step 6: Mount the candy chute to the front of the base plate using M3x8mm screws, positioning it to catch dispensed candy.

  7. 7

    Step 7: Slide the 4mm dowel axle through the left axle mount hole.

  8. 8

    Step 8: Press the large gate disc onto the axle, then attach the custom dispensing gate piece.

  9. 9

    Step 9: Continue the axle through the right axle mount and press the handle disc onto the protruding end.

  10. 10

    Step 10: Test the mechanism by turning the handle. The gate should rotate and align its opening with the hopper outlet.

  11. 11

    Step 11: Fill the hopper with small candies or treats through the top opening.

  12. 12

    Step 12: Turn the handle slowly to dispense candy through the chute. Your candy dispenser is ready to use!

About This AI-Designed Building Kit

This Sweet Treat Dispenser kit was designed entirely by artificial intelligence based on a young inventor's idea. Every InventShack kit features precision laser-cut 1/8" birchwood plywood panels, custom 3D-printed PLA components, and real M3 socket head cap screws with hex nuts — the same hardware used in real engineering projects.

Unlike mass-produced building kits, this design is one-of-a-kind. The AI selected from a library of parametric component templates — base plates, side panels, wheel discs, axle mounts, rubber band hooks, corner brackets, and more — then configured each part's dimensions to create a working build. All holes align to a 10mm grid system, ensuring every part connects properly.

Perfect for kids ages 8-10 who love building, inventing, and engineering. Whether you have a laser cutter, a 3D printer, or just want to see what AI can design — InventShack turns kids' ideas into real, buildable projects.
