3D Printable Folding Micro FPV H-Quadcopter
I have been designing a lot of things for almost a year now. It started out as designing custom parts for my own builds but I am now working on things that I will share or sell. Here is the first creation that I am ready to show off.
About 2 months ago I got a 3D printer, the MakerGear M2. Before that I was spending a lot of money to have Shapeways print all my little parts. It has been amazing to have my own (reliable) printer that I can draw up designs and immediately start making them into physical parts. Even better, I can keep refining designs at very little cost.
Micro H-Quad frames have become very popular lately for FPV flights. Years ago I built similar sized (5″ prop) quads and didn’t have very good luck with them. At the time the motors and props available for multi-rotors of this size were hard to find. The motors most used were very cheap and had poor bearings, were unbalanced and thus created lots of vibrations.
Fast forward to today there are about 5 motors that pilots are building their micro quads with:
- SunnySky X2204S (what I am using)
- RCX 1804 (heard these aren’t that great)
- Lumenier FX2206-13 (good but more expensive than Sunnysky)
- Tiger MN-1806 (most expensive)
- Turnigy Multistar 1704 (hear mixed reviews on these)
So why print my own frame? Most of the micro FPV quad frames out there cost about $100+. This size of a copter lends itself to being perfect for a fully printable frame. Also, using this software, I calculated that printing all the parts for my designs costs just under $4 in filament!
So here it is, designed to fold up (without tools) for compact storage & transportation, integrated vibration dampening, loads of mounting options for a Mobius or GoPro camera, electronics and so on. Frame weight = just 116 grams! I just assembled this first prototype last night and have done some short test flights. Waiting for the rain to subside so I can tune the flight controller and do more test flights. Initial impressions are jello-free video footage and everything is fitting together great.
