I needed a light weight 1/4-20 bolt for the quad copter. I was able to create my own with mike-linus's threading tool thing. I'm nothing but impressed! Thank you Mike! Once I figured out how to work it, its really cool! Now, how about socket cap screws?

Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=193647

NOTE : Print it in High quality. I"m currently using 2 shells & 50%. Seems to work well. Standard quality setting doesn't do a good enough job on this.
