ThumbDrive - 19mm-3/4 - Pocket Screwdriver

This is the ThumbDrive Pocket Screwdriver.

This model uses a 3D printed ball detent to retain a wider variety of ¼inch screwdriver bits. 

No more magnets, friction fit, stuck or dropped bits. This model prints in place and works right off the build plate!
 

Please allow model to cool before inserting a screwdriver bit. if the detent is pushed while still hot from the print bed, it will not spring back with the correct amount of force.
