I'm a novice maker, so I decided to start with a easy project. So I used the original spring in my old spindle. I found that not only does it work well, but it can actually be used as a launcher if you get bored. Haha!
What the chances of this actually being featured on Thingiverse?????
Just tear off a couple of sheets and.... Oh,oh wait!! You mean how do you use the printed TP spindle.
