Pumpkin Theme Toy Train

This pumpkin themed train was designed and 3D printed for my Advanced Engineering and Design class project. My fellow classmates were tasked with designing our own trains with the goal of making them link together for a final product. We decided to go with a halloween themed design because it was around October when we started. My designed is based off of a pumpkin and my other classmates designs were inspired by ghost, witch, and skeleton.I am a student at Bencia High School.

Supplies

• Finish Nail 1-1/2" (4)
• Decotacks Silver Finish Upholstery Nails, Furniture Tacks, Thumb Tacks, Push Pin, 7/16in (2)
• Bolt cutters
• Wire cutters
• 3D Printer (this was printed with mainly the Ultimaker 2+)
• Filament (Ultimaker PLA Filament - 2.85mm if you want to print a Halloween themed version, but other filaments work too.)
• Any type of super glue
• Magnets
• M4 Screw 16mm

Step 1: Parts Needed

• 1 Train body
• 1 Train top
• 1 Pumpkin
• 2 Pumpkin pieces
• 8 Train wheels
• 2 Train base

Step 2: Print the Train Body

• Start off by printing out the body of the train

Step 3: Print Out the Train Top

• After printing out the train body and train top, assemble the pieces together
• Place the pegs on the train top into the holes on top of the body

Step 4: Print Out the Pumpkin

• Once the body and top have been assembled, then place the pumkin into the designated hole on top of the train top

Step 5: Print Out Pumpkin Pieces

• Once the two pumpkin pieces have been printed out, you then place the pieces onto the side of the train body. There is one hole in the middle on both sides

Step 6: Print Out Train Base

• After both of the train bases are printed, hold onto them

Step 7: Print Train Wheels

• After all 8 wheels have been printed, hold onto them

Step 8: Cut the 1-1/2" Nails With the Wire Cutter and the Bolt Cutter

Use the wire cutters to make a mark for the colt cutters to cut the nails. Cut them to about 11.85" or 30mm in length.

Step 9: Attach the Nail Into a Wheel

• Glue one end of the nail into a wheel and have it sit up so the glue can dry correctly in place
• Once dried put the end of the nail without the wheel into the train base
• The glue the other wheel onto the end of the nail
• Repeat the steps for the rest of the wheels and base

Step 10:

• Attach the train bottom to the train, then screw on the train bases onto the train
• 4 rotations is recommended because you do not want the screw to be too tight

Step 11: Assemble the Magnets

• I do not have a photo to show of the magnets being assemble but it is very easy
• Place the magnet into the case on the train base (make sure to be aware of the magnets charge so it can attatch to other trains properly)
• Use the pin to keep the magnet in place

Step 12: Build the Rest and Enjoy
