8mm ACME leadscrew anti-backlash nut
thingiverse
This is an anti-backlash nut engineered specifically for an 8mm, four-start ACME leadscrew. The design builds upon Tyler Montbriand's outstanding TSM thread library, but I found it necessary to adjust the thread measurement by tiny increments of 0.1mm until a precise fit was achieved. You can likely expect to make similar adjustments. A suitable spring is also required to maintain tension between the two parts, keeping them securely locked together. The provided STL file serves as an example and should not be used for actual production purposes.
