extended leg for F450 size quadcopter

thingiverse

I had been looking for extended legs for an F450 qudcopter clone. I was converting it for aerial photography and need room underneath for a camera gimbal. Originally I printed the legs by lijbotero at this link - http://www.thingiverse.com/make:237142 These were great but I needed taller so I modified them to make them longer but the problem then were they were quite flimsy. Unfortunatly one of the legs broke on the second flight so I decided to design my own using lijbotero's design for inspiration. The result can be seen in the pictures. I didn't intent there to be a the opening in the middle of the legs but I liked it so I left it as it was. I had intended to put some structure in the gap to provide additional strength but it doesn't seem needed. As you can see you can fill this gap with something useful such as your 'handle', email address or telephone number. Useful if you have a fly away and lose the quadcopter. Now who ever finds it could have a way of contacting you. (see design section.) Print Settings Printer Brand: RepRap Printer: Prusa I3 clone Rafts: Yes Supports: Yes Resolution: 0.2 mm Infill: 35% How I Designed This I designed this in Fusion 360. I took a picture of quadcopter arm and loaded that in as a canvas and sized it to the correct size. I then used the sketch tools to draw the pocket the arm fits into and the outline of the leg. I then extruded the sketch to match the sizes needed. 2.5mm sided to the pocket and a 7.5mm gap for the arm to fit in. This gives an over all thickness of 12.5mm. To add the text, I exported the outline of the leg (the dxf file included) and loaded it into inkscape. I then wrote the text, combined the letters into an path then used the envelope path effect to match it to the internal shape of the leg then saved the text path as a svg file and imported it into Fusion 360 and extruded it by 6.5mm inserted into the leg and combined the shapes.
