SFU1204 ball screw nut remover and transportation chuck

thingiverse

If you ever wanted to remove the nut of your SFU1204 ball screw here is the appropriate removal and transportation tool. Now you can check your ball screw whether it is bent or straight without paying attention to losing the nut. Especially when using the cheap ball screws from China this should be checked! The upper hole is 8,1 mm in diameter and properly fits onto the ball screw, otherwise just sand it a bit. Before unscrewing the nut properly align this tool so that the groove on the crossing point is looking the same as on the ball screw itself. This can be achieved by slightly rotating the tool on the ball screw. Have fun. Edit - 28.05.2021: I added a version with both ends being open so you can screw the ball nut onto this chuck and flip it to screw the nut back onto the spindle in the opposite direction. This version has the bottom hole tapered so it can still being printed without any support.
