Climb On: Uniting the Climbing and Engineering Worlds

I, Peter Kreuch, am a junior at Darien High School in Darien, Connecticut. I am an avid climber and runner and dream of someday working as an engineer. This past semester I embarked on an independent mechanical engineering project.

I sought to design a user-friendly hang board that could be easily produced using a CNC milling machine. By utilizing my math and science skills, my engineering knowledge, and my experience as a climber I was able to design the hang board and create a working prototype. This project was challenging, interesting, and enlightening. I was pushed to improve my design skills, to master Google Sketch-Up, to familiarize myself with the CNC realm, and to expand my engineering knowledge.

Attached are the original design files. Please email me at if you would like the g-code and .stl files. The hang board can be milled out of any material, however, wood or polyester resin have proven to be the most popular. Once the board is milled edges should be sanded based on user preference. To mount the product one should drill into the board based on their preferred mounting set up.

I hope that this product proves to be user-friendly, ergonomic, and effective. Feel free to edit the design or to provide feedback. Any questions can be sent to Thanks!

Right on dude!

Keep at it!


All of the "Slots" in your diagrams look to be very similar. I see no advantage to having so many of similar size, and angle.

Think your file/ design needs more work.

If you are going to spend all that time milling and the investment in the material why wouldn't you add the fillets and sloping surfaces while it's on the machine? I know that sketch up is a very limited program though...

Locker is right on the variety, there needs to be more.

Also you might want to read up a little on orthographic projection/ the correct naming for your views.

I'm no CNC programmer, but could help a bit with some of the layout in Solidworks easy enough, that'll feed into any of the popular CNC software.

If you're looking to prototype and refine your design and don't mind working with hand tools, you could make what you have drawn there with some basic wordworking tools - Primarily some chisels for carving the pockets.
