Screwdriver Handle

This is for a screwdriver shaft that has the two flattened tabs on the end (see picture). It took me awhile to dial in the inside diameter for the screwdriver shaft and I left it so you must use some force when installing for long term use. 

Print Instructions: Print with a brim (8mm recommended) and 3 perimeter shell/wall count. Infill depends on how long you want it to last. I did 50% with PLA but will probably make another with higher density in ABS. 

Specifications: Shaft diameter is 0.25 inches.

Updates: Decreased handle diameter, corrected shaft hole diameter.
