Do you have too many 2.5mm Allen/hex keys? and hate using them because they don't have a good handle. Well boy howdy, do I have the answer for you. Simply slide in your old hex key. run three pieces of old filament through the holes in the handle and locking plate. and hey presto- You've got a new screwdriver. Inspired by that other popular design, but modified to make more sense for me and my shop and to avoid using zipties
