A grip I made for small 15cm metal saw blades.
I made this since I needed to saw a metal pole and didn´t want to buy a saw grip :)
It works pretty well and is easy to hold without cramps.
You just have to insert the pins on one side of the saw blade into the space which points straight down (picture 2) and then bend the other side of the grip a bit inwards to fix the free pins into.
The print takes only a couple minutes, just remember to print it laying flat.
