M1.6 nut driver for tightening and loosening M1.6 nuts. It's compact in size and is hollow to allow a shaft to go through the middle if needed. Great for small scale radio controlled vehicles that use M1.6 fasteners and wheel nuts.
It is important to ensure your printer is dimensionally accurate when printing to ensure that a M1.6 nut will fit snug. Using a smaller size nozzle such as a 0.3mm or less is recommended.
If a nut does not fit all the way, place it on flat and tap it with a hammer to get it to fit. You will probable need to thread the nut onto a shaft and pull to remove it. The driver will get better with use as it gets worn in.
