Wow this is pretty awesome! Thanks for sharing!

Very nice, I always wondered how to 3D print a dual state pen mechanism like that. I'd still use ball pen springs but it's a very nice design.

Thank you :) However, it's still incomplete. There's no possibility to add some cables to it yet. Unfortunately my printer has a defect atm and I just don't have enough spare time to get it running again :(

It turned out very well! It seems a little brittle at some parts, like the latch and the clips on the outside of the walls, but the mechanism works really well.

You might want to print the spring in nylon. It's much more resilient than PLA or ABS.

Unfortunately I only have one extruder atm which is set to PLA, so I have no way of testing it in nylon or even ABS. Please tell me your experience if you print it sometime

Great idea! (Just be careful of contact arcing if it's ever used with anything that is not low-power.)

If you're having problems with the current spring, try a squashed compression spring design, that might work better

What do you mean with squashed compression? Do you have an example?

a thing like this would help:

And I assume that since you made the switch you could figure out how to edit that to your needs.

Device to produce PLA springs

Brilliant. Beautiful. Well done.

im assuming you used sketch up to design this... how did you create such uniform springs?

There's a sketchup plugin called "Fredo6 Bezierspline". I used the FSpline tool for the base line of my springs.

Thanks a lot :) I'm having a lot of fun playing around with springy things right now.
