I wanted to have my students make something that would help them understand how a lock worked. I found the pattern from Matthias Wandel and made it so that my laser engraver would cut out most of the parts. I plan to use this project next year so I have the summer to make any improvements. Let me know what you think. I want to make this into a mass production project where each student makes a part and then passes it onto the next station.

Sounds like it should be fun. Maybe the students could sell them as a fundraiser…

As a retired shop teacher, I love what you are doing. I can imagine that the kids will also.

I seem to remember that Matthias’ version or some similar version that would reset the combination wheels when the lever to open it was actuated. That would be good so candy can only be received once per activation of the combination.

There is a similar machine on Matthias’ site at This version uses a rotation gear wheel to dispense the candy.

I know you are trying to work out all the bugs. I also know that you have to teach it one or two years before the activity works real well so hang in there.

Let us know how it works out.

That is a great idea for class! I know of a guy who is looking to demo 3D printers to HS students to get them excited about the technology and I may pitch him on this very idea. Obviously most parts would need to be pre made, but the kids could program the printer to make key missing elements and then assemble the works.

Really great thinking and thanks for the inspiration!

This is a great project and it looks like it would be a lot of fun to make and use one.
