Hex Key handle collection for metric Allen Keys and 3D printers

This is a set of handles that fit metric hex keys (Allen Keys) in sizes 1.5mm, 2mm, 2.5mm, 2.5mm, 3mm and 4mm (the same sizes you get with many 3D printers). They are very simple and easy to use and can be used either in a T-handle or as a screwdriver. There's no need to cut down all your spanners and you can easily remove the spanner to use it normally.

Ideal for those of us with larger fingers, they make it easier to get a grip, apply torque, especially on smaller, hard-to-reach fasteners. Perfect for taking apart your hot end... or assembling Ikea furniture.
