2mm Hex wrench - fits over 90% of the screws on the UM printers (UMO, UM2, UM2+, etc). Incredibly helpful - saves lots of time versus using an L shaped wrench! Ball end allows up to 20 degree angle when tightening or loosening screws.I just learned after using 2mm hex wrenches for 2 years that the 3mm screws actually have 2.5mm hex sockets in them. Not 2mm. However I have been using 2mm wrenches on the 2.5mm sockets all of the last 2 years (thousands of screws tightened) and they work great. Also the pulleys *do* have 2mm hex socket set screws so if you only have one tool make it a 2mm. You can tighten the M3 screws all over the printer with this tool to a high amount of torque - they don't slip. It's a great tool. I've never had one slip.
I've been using only these hex drivers that I sell this past month and have taken apart several heads with it and put them back together - same with several feeders. These hex drivers work great!
