5x3 bullnose props

thingiverse

material - PLA WHO SAYS YOU CANT MAKE PLA PROPS!!! My own simple bullnose design, performed far beyond my expectations even without balancing and only the most bare essential finishing with a craft knife to remove some stubborn brim fragments post print. I even chucked in a couple of flips on the second flight and the props held rock solid (even when I pushed my luck on a third flip a little to close to the ground and frame came down on its arm embedding a prop blade in the soil.... no damage) RESULT! https://youtu.be/l38aqKbnbvo also worth note that Im testing them on a 350 frame in that video which is generally oversized and slightly overweight for 5" props but they still held up admirably. Print Settings Printer: Colido Printrite diy 3d printer (ramps 1.4) Rafts: No Supports: No Resolution: 0.2 Infill: 30% Notes: use brim of 5mm minimum as blades obviously dont have a big enough footprint for solid bed adhesion otherwise. suggest setting extruder temp near to your filaments advised upper thermal limit as theres very little chance of "stringing" with these designs during printing and you really want to maximize layer bond.
