The leadscrew should still rotate very easily, so if it doesn't, loosen the screw a little.</li> </ul> <p>Source of the original model: <a href="https://openbuilds.com/projectresources/anti-backlash-nut-block-step.153/">https://openbuilds.com/projectresources/anti-backlash-nut-block-step.153/</a></p> <h3>Print instructions</h3><p>0.4mm nozzle<br/> 0.2mm layer height<br/> 5 perimeters<br/> 5 solid layers on top and bottom<br/> supports off</p> <p>material: something hard, low friction and slow wearing.
