It turns out the rotors are available separately (as are the bare boards actually, see left). So I started wondering about how I might go about designing one. As a first step I measured the quadcopter and put the above design for a frame together (design files below). I&#8217;ve sent it out to dirtySLA (which cost a massive 4USD! :)) for fabrication.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"http:\/\/41j.com\/blog\/2016\/01\/3178\/fullsizerender3\/\" rel=\"attachment wp-att-3183\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3183 aligncenter\" src=\"http:\/\/41j.com\/blog\/wp-content\/uploads\/2016\/01\/FullSizeRender3.jpg\" alt=\"FullSizeRender(3)\" width=\"348\" height=\"358\" \/><\/a><\/p>\n<p><a href=\"http:\/\/41j.com\/blog\/wp-content\/uploads\/2016\/01\/quadcop.stl\">STL<\/a><\/p>\n<p><a href=\"http:\/\/41j.com\/blog\/wp-content\/uploads\/2016\/01\/quadcop.sldprt\">SLDPRT<\/a><\/p>\n<p><a href=\"http:\/\/41j.com\/blog\/wp-content\/uploads\/2016\/01\/quadcop.dxf\">DXF<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I picked up a CX10 mini quadcopter on eBay.
