Roll Pins

[jmccartney]

   
I was curious to get opinions on alternative fasteners. I was thinking this morning (dangerous) about when I built my AR-15 and how some components used "roll pins". They were horribly annoying because they tend to bend or deform.

I don't see any examples of PLA roll pins on thingiverse. Is this because its not possible to do? In my head they seem like they could work and would be better than "snaps" and tabs for certain things.

I am not sure "roll pin" is a international term. This link has what I am talking about http://en.wikipedia.org/wiki/Spring_pin towards the bottom under "slotted spring pin".

(FYI I have also used the "coiled spring pin" depicted on the wiki page, they are much easier and reliable to work with but probably not practical for printing)
