Hi
I am looking to build a prusa i3 3d printer and I was wondering what spring is used in the design?
It calls for 2 of springs in the bill of materials and it does not say the size.
Thanks
Tanner

I saw someone used springs from inside pen for the extruder/filament spring load smiling smiley

That's about the type needed ....

I've got biro springs on the bed and they work fine. You'll probably want something stronger for the extruder, you want to push the filament against the hobbed bolt/gear pretty hard to ensure it doesn't slip.
