While looking for Mini H Quad frames for me and my Dad, I came across a website called http://untestedprototype.com/ who have 9 sets of plans all in DXF format for being mill on a CNC. I do not have a CNC mill but I do have a 3D printer so I decided that i wanted to try the Hammer Mini H Quad v3.0 frame first. I have converted the DXF files into STL files using Rhino3D. Thickness of parts have been assumed but not tested yet! I am very new to 3D modeling and printing so things may not be correct all the time, advice is appreciated. Feel free to print these on your own printer and leave a comment on changes that should be made. v3.1 Changes - 24/04/20134 Additions Different arms have been added, they have cutout for the motor wires to pass and a spacer. Required = 4 X Arms 1 X MainBot 1 X MainTop 1 X Top 1 X Mobius 2 X Landing Motors: RCX 1804 (2400KV) Micro Outrunner Brushless Motor (Clockwise & Anti-Clockwise) Propeller: 5x3 2 Blade ESC: Afro ESC 12Amp Multi-rotor Motor Speed Controller (SimonK Firmware) Flight Controller: AIOP V1.1 ALL IN ONE PRO Flight Controller Receiver: FrSky V8R7-II 2.4Ghz 7CH Receiver The build manual from untestedprototype.com should be used for the acual assembling of the frame (remember that the thicknesses will be different) http://untestedprototype.com/2014/03/hammer-mini-h-quad-v3-0-manual/ I am currently printing the parts in PLA @ 80% infill
