16T Idler Pulley

I recently purchased some 16T idler pulleys for my first printer, they cost me around $8 US. It wasn't much but this cost me around $0.10 if not less, with being able to print a infant about of them also. These will work on any application using a 16T pulley, they where based off the ones I purchased and designed in fusion 360. I hope everyone enjoys!

Edit: For best results remove the threads on the screw you are using. I noticed the tension from the belt would make it go back and forth.
