Plinko Board

In school, three teammates and I were tasked with designing and building a homemade PLINKO board. Through collaboration and careful planning, we created a finished product we were proud of. In this Instructable, I will show you how to build your own PLINKO board step by step.

The supplies needed for this project include a 3D printer, a 1 ft by 2 ft wooden board, a 4.5-inch by 2 ft wooden plank, a 4.5-inch by 14-inch wooden plank, and a plastic or other clear material for the bottom section. You will also need the following 3D models: Plinko Board – Fully Assembled.

Find a plank of wood and cut it so that it is 2 feet tall and 1 foot long.

Next, cut out the edge borders so they are 2 feet tall and 4.5 inches wide. Attach one border to each side of the main board piece, ensuring they are aligned evenly.

Next, using the 3d models provided earlier, print out the triangle borders. 10 of the normal triangle ones, and 2 half triangle edge boarders.

Next glue the triangle borders to the edge boarders or the inside of the PLINKO board.

Next print out 80-85 pegs and glue them 1 inch apart from each other.

Next, print a bottom piece with dimensions of 14 inches by 4.5 inches by 0.5 inches. This piece will serve as the base where the disc or ball lands. If a 3D printer is not available, you can instead cut a wooden plank to the same dimensions.

If you have a 3D printer you can print out the bottom piece in two different parts. If not, then cut out a wood piece with those dimensions and then

Next, glue the bottom dividers in the slits on the bottom piece. if you had to cut out a plank, just put the bottom dividers on top but with what you think is a good distance apart for each point amount.

Next, find a flexible, transparent material to use as the front covering. Position this cover about one inch above the bottom piece so the disc or ball can be easily removed by tilting the PLINKO board forward and allowing it to fall out.

Next, you will need a small marble or ball that can be used as the dropper. If you don't have either of those you can use the PLINKO disc 3d model instead, but a ball will work much better.

The final step is to find a wall or sturdy structure to lean the PLINKO board against. This support prevents the disc or ball from falling forward when it is dropped.
