Replacement slider part for a semi-common recliner actuator. This was actually the reason I built a 3d printer in the first place.

I printed it in PLA with 4 shells, and 0.15mm layers and 30% honeycomb fill. The part has threads, which turn out much better with thin layers (much less overhang.) These settings make it take long time to print, but the final part is very strong.

The plastic part in the pictures is the broken part that I replaced.
