3D Printed Peg Jump Game With Magnetic Box

Hello! I will be going over how I made this 3D-printed peg jump game, based on the Cracker Barrel peg game. In addition, I included a magnetic box to store the pegs so that you can play it while on the go (camping, airplane, car rides, etc).

How to Play:

• Start by putting all the pegs into holes. One of the holes should be empty
• Jump an adjacent peg and remove the peg you jumped over (note: you can only jump a peg if the hole on the other side is empty)
• Keep jumping the pegs until you have no moves left. The goal is to have one peg left

There are many ways to solve the game (37,260 to be exact), so keep trying and you will win!

I like to play this game during my free time because it stimulates my brain, helps me relax, and is a good alternative to scrolling on my phone.

CAD Software

3D Printer with filament

Slicing software with pausing capabilities

Neodymium magnets (these are the ones used in my design)

Using Fusion 360, I designed the the box and the pegs. To account for the magnets I embedded in the print, I sketched and toleranced the holes then offset the extrusion by 1mm, and cut the part. The cuts are visible with the hidden line visual style.

Using the Bambu Slicer, I imported the files and sliced them. I scrolled through the layers and added a pause at the last layer of the hole. What this does is stop the print so that I can put the magnets in.

NOTE Make sure to add two pauses: one for the hole on the top part, and one for the hole on the bottom part since they are at different heights.

Afterward, I resumed the print, and the magnets became embedded in the print, resulting in a cleaner look. I am not sure if every slicer has a pause function, but Bambu has one 👌.

If you look at the cover picture, you can tell that one of the magnets is DEFINITELY exposed. It wasn't intentional though. One of the magnets just got stuck to a part of the extruder that was magnetic, so I had to hammer it in afterward.

I also printed 14 of the pegs.

Overall, this was a very fun project to do. I have never incorporated magnets into my 3D prints before, but the process ended up being pretty straightforward, and I look forward to using more magnets in future projects. I hope you enjoyed reading through my Instructable, and I hope you print my design and play the game for yourself (please post it below if you do)!
