T8 Flexure Preload Anti-Backlash Nut Block
A 70 x 56 x 30 mm carriage block that holds two T8 brass leadscrew nuts, one on each end face, and removes backlash by pushing them apart. The end plate for the second nut floats on a pair of parallel 1.6 mm flexure blades: squeeze it about 0.3 mm in a vise, bolt on the nut, and the blades hold both nuts against opposite flanks of the thread. A 0.8 mm hard stop stops the blades from being bent too far, and radial M3 slots (r 7.5–11.5 mm) fit a range of nut flange patterns. It mounts on a carriage with four M3 heat-set inserts underneath.
Linear Actuator Swivel Clevis Mount
A print-in-place two-axis end mount for 12 V linear actuators: a 64 x 56 mm base flange with four M5 clearance holes carries a captured swivel yoke that yaws a full 360° on a printed post, while a 22 mm wide clevis with an 8.5 mm cross bore takes the actuator's own 8 mm rod-end pin 19 mm above the mounting face. It replaces the brand-specific bracket-and-pin kits that cost as much as the actuator, and the free yaw axis stops cheap actuators from binding on vent flaps, coop doors, gates and solar trackers. Overall 64 x 56 x 36 mm; the yoke and base print as one piece with 0.4–0.5 mm running clearance and cannot be pulled apart.
Rack And Pinion Linear Drive Block
A print-in-place module-2 rack and pinion linear drive: a 150 mm toothed rack slides through a 60 x 54 mm housing while a 16-tooth pinion (32 mm pitch dia, 100 mm of travel per turn) turns on a 5.3 mm bore for any 5 mm motor or gearmotor shaft, locked with an M3 screw into a captured M3 nut in the top collar. The housing bolts down through four M4 clearance holes and the rack carries two pairs of M3 heat-set bores on top for your carriage — a cheap linear actuator for gate, hoist, feeder and camera-slider builds where a leadscrew is too slow.
