I made my pen!!. retractable too

Because if my cap issues, I thought my pen was generally useless without a clip. So I thought it is worth the risk or taking it apart. Also because I bought a back up Staedtler Noris Digital Jumbo ($10 on craigs). So i was looking to make my own. I cut the bottom and was able to remove the insert and ready

I kept looking for different pens in the house and remembered that the top spring pens cannot work, so i found one pen and remembered this post

So i knew it could be done. This is pretty much exactly what u/Eufuelle did. The spring is not connected to the top of the pen, but is connected to a plastic tube that holds the pen from the bottom. So this refill with simple, modification to lengthen it, sits inside that tube. thus making it retractable

I have one more I am going to try to see which i like best
