The iHSV57 ring prints as one piece but snaps into two halves after removal from the printer. Clasp each half around the motor to assemble.

iHSV57 motors smaller than 180w require modifications to the ring design.

Print Settings

Setting	Value
Walls	6
Infill type	Cross Hatch or Gyroid
Infill percentage	10%
Supports	Tree Supports, 5° threshold angle
Seam	Nearest (or your preference)
Filament estimate	~150g
Recommended filament	PLA+

Print all parts in the default file orientation. Printing base components in other orientations causes structural weakness.

Required Printed Parts
