Material: PLA Layer Height: 0.2mm Shell Thickness: 0.8mm Fill Density: 20% Print Speed: 70 mm/s Printing Temperature: 220 C No printed supports necessary. IMPORTANT NOTE: Blade side MUST have blade in place during printing. Place the blade in the cavity during the print once the layer height matches the blade thickness. This will ensure a tight fit and keeps much tighter tolerances than can be printed in a flipped orientation. (See included image or full product page.)
