This is a three-layer adapter that allows your gaming chair armrest to slide (up to 90 mm) and rotate (45° each way). It features two independent locking mechanisms — one for slide retention and one for position fixing.
🔧 Components
BOTTOM_BASE – Base plate attached to the original arm mount.
MIDDLE_SLIDER – Sliding element providing 90 mm of travel.
TOP_PLATE – Upper cover and armrest interface plate.
SLIDE_LOCK_LEVER – Prevents the slider from slipping out. Lower the lever during installation, then raise it in the center position to lock. Print horizontally (on its side) and enable supports for best strength and accuracy.
POSITION_LOCK_LEVER – Locks the slider at any position and provides tactile “click” feedback during sliding. Can be omitted if a smoother motion is preferred. Print horizontally, no supports required.
⚙️ LOCK_PIN – Provides detent feedback (“click” feel) when rotating the armrest. Optional if smoother rotation is preferred.

The dual-lever design offers smooth sliding when needed — and firm locking when not. Printing both levers horizontally ensures maximum strength; only the SLIDE_LOCK_LEVER requires supports.
