can anyone tell me how to make a clicking pen mechanism? Answered

would anyone be willing to tell me how to make a simple clicking pen mechanism?  my son & i thought it would be fun to insert them into various common household objects to use as novelty pens.  any suggestions would be appreciated!



use a pen, or copy the mechanism in different materials.


It may be simplest to sacrifice commercially-made pens and use parts from them rather than trying to build this yourself.

Or you could come up with a different mechanism to extend and retract the cartridge.

Or you could make a pen that doesn't retract, with or without a cap. I have a letter opener on my desk right now that also contains a pen cartridge; they didn't bother with either retraction or cap.

Take one out of a pen and see how it works. This might give you an understanding of how you can make it.
