Tevo Tornado Bed leveling screw stoppers - bushings

thingiverse

This is BUSING / NUT for counteracting the free rotation of the BED LEVELING SCREWS on the TEVO TORNADO 2018 GOLD,\ This may also work on the GREEN older model, but not tested. Please test print , and see if it fits, as tolerances are very small, and material expansion can be different. If the screw still rotates freely after tightening untill it reached the glass bed, then the inner diameter of the bore should be resizes to a smaller value, 0.1 mm for example. Please insert the bushing all the way in the screw hole before installtion, and DO NOT OVERTIGHTEN! This piece will not last forever, and will need constant replacing, as it will ware out. I have tested it for some time now, and all seems ok, and not changed them in 2 weeks. IMPORTANT NOTICE: If printed in PLA, after some bed heat cicles, these will become very flimsy eventually. If bed is heated to above 100C for ABS printing these will need thightening a bit before leveling!! I have also noticed that Mr. vektorviktor has a similar design, but for a different purpose: https://www.thingiverse.com/thing:2848079 Check that out too!!
