Help needed with ceiling fan design please

Greetings! Currently, I am engrossed in designing an innovative project but facing difficulties with the 3D modeling of my concept, which revolves around Chinese knots and Mobius strips. Despite having made a model using ABS, I am still struggling to get accustomed to 3D modeling on Solidworks. My presentation is scheduled for Monday, and any advice, tips, or guidance would be greatly appreciated. The design features a ceiling fan with two interlocking blades, each made up of two shapes that meet at the ends. The first shape, an S-curve, sits on top, while the second shape is a twisted C-curve. The S-curve and C-curve join together at the ends to form a Mobius-like strip. Could someone kindly assist me? I have not been able to find similar models online, and I can provide pictures or Solidworks files for reference. Thank you, Riaan.
