Idler For Short Bolts for Airtripper Bowden Extruder

I was previously using some M3x40 bolts for tensioning the idler on my Airtripper extruder, but needed to scavenge the long bolts for a different project. This idler was designed to allow for the use of shorter bolts. I'm currently using 30 mm bolts with springs, but you could use shorter ones (down to ~20 mm) depending on if you're using springs and their sizes. Hope that this might help someone else.
