propeller truing tool thing

thingiverse

this is a truing stand for propellers so you can make em straight when you have crashed with your fpv racing drone. you print some size 20,25 or 30 mm lip and then you file it down to the right size for your motor and propeller size. And you can make the propeller straight. I included the fusion 360 file so you can modify it if you want. you take a burned motor or something and use it to mount the propeller on... I even toke and sawn down the axle a bit so it was easier to mount the nut and remove it.
