I had a look at some of the prop guard designs, but thought they weighed too much and also had a problem where they would strip the motor wires as they were slid on. RC-King's version has been designed to be both light weight and springy with more than sufficient clearance for the motor wires. You can download and print these here or visit our website to buy them out right. http://www.rc-king.co.za/cheerson-cx-10-spares/427-cheerson-cx-10-prop-guards.html I print these at a 0.1mm height using florescent green ABS. The light combines in the material and give a great look. I typically print 5 at a time to ensure each layer gets a chance to cool down. You want to make sure that your printer is well calibrated as this is an extremely small print.
