Best for Printer assembly and maintenancetightening frame and belt boltsnozzle and hotend screws

3D printers are held together with metric hex bolts, and the little wrenches in the printer box are usually soft and round off after a few uses. A good set of hex keys makes maintenance less painful: tightening the frame, adjusting belt tension, swapping a hotend.

The ball end lets you turn a bolt at an angle, which helps with the screws that sit behind a fan shroud or under the gantry. Use the short straight end for breaking a bolt loose or for the final tighten.

Pro tip Go through every frame bolt on a new printer after the first few weeks. Bolts loosen as the frame settles, and a slightly loose frame shows up as wobble and layer lines.

Why we like it

✓Ball end works at an angle, for bolts behind the hotend or frame
✓Nine metric sizes, 1.5 to 10 mm

Keep in mind
