I design this handle to hold the hex driver that came with my quadcopter kit. The design was meant to hold a M2.5 hex driver. A flaw in the design, I wrongly estimate the turning radius of the angle causing the long side of hex driver unable sit in the center. I did later order the hex driver set online but that took a while to arrive, so meanwhile this handle does come in handy.

I printed using nylon filament, but I couldn't seems to get the settings right and print perfectly.
