Toy Quadcopter / Drone - Dual Prop

prusaprinters

<p>Thanks to pefozzy for the base model!</p><p>The props have been changed to dual prop - same internal hole diameter as the original so the pins can bit fit and glued in the same manner.</p><p>The image shows glow in the dark props (kids found it fun).</p><p>The attached base is plain - not lettering or shape.</p><p>To add a letter use something like Meshmixer (maybe there is a better way to do it, but this is what I found):</p><ol><li>Import the base model</li><li>add the letter shape and change it sizes</li><li>re-mesh the top of surface of the base where the shape goes (select and re-mesh) and the letter/shaper over and over for lots of triangles (as much as your computer will handle)</li><li>make the base see through with a shader (or letter/shape) and lower it to make an indent.</li><li>in the object browser (under View) make sure to FIRST select the base and then your letter/shape and the do a boolean difference (set it to as accurate as your computer will handle).</li><li>Test for any holes with the inspection tool and fix stuff. Export to STL and print.</li></ol><p>&nbsp;</p><p><strong>Print Settings I used:</strong></p><p>Printer brand: Creality</p><p>Printer: Ender 3 Pro</p><p>Rafts: No</p><p>Supports: No</p><p>Resolution: 0.12</p><p>Infill: 40</p><p>Filament brand: eSUN</p><p>Filament color: Light brows and glow in dark</p><p>Filament material: PLA+</p><p>&nbsp;</p><p><strong>How I Designed This:</strong></p><p>Lots of playing around in Meshmixer: (this is probably easier in cad if you know cad)</p><p>The props i basically import the triple prop and made 2 copies. Spun around one 60 degrees so the props arms faced each other.<br>Now you need to get a center pivot in that center ring. Just select the internal walls (all of them) and extract a copy and raise it up from the model. Add a pivot to be used later.<br>Now cut away the side props leaving only 2 arms facing away from each other.This leaves gaping holes on the sides of the ring.<br>Select a a remaining out wall that is more or less a square and select the previously made pivot. Pivot around the pivot making copies (press D) all around the ring to cover it.<br>Finally make the shape solid with a the smaller offset it will give you (0.01) and use the inspector to solve any issues.</p>
