105mm Micro Quad w/ CFF by The_Cheat

Last crawled date: 4 years, 7 months ago
This a remix of the popular Micro 105 FPV quad. The intent of this remix is to make the arms wide enough (3mm minimum) to put continuous strands of carbon fiber in as I am printing quads on a Markforged Mark Two. I also feel like it looks a bit less toyish than the standard frame with the single arms, but that's just personal opinion.

I was breaking a lot of ABS frames (just learning to fly, not very good yet) so I switched to nylon. While fantastically crashproof, the nylon v3 frames were very floppy which wasn't great. My work got a Mark Two recently so I figured this would be a good chance to take advantage of the shorter CFF length it can do vs. the Mark One.
V1 frame weighed in at 7.75g for top and bottom, is stiff enough (for me) and is entirely crashproof, I challenge anyone to break one of these frames. V1 base only has fiber in the arms, it did not path to the center of the frame. It is pretty flexible but once assembled with the carbon reinforced upper deck it gains a lot of strength.
I have yet to print V2/3 but it has been revised to use less nylon on the motor mounts (but requires a tiny bit of thin tape to hold them, I plan on using Kapton) and has carbon fiber pathed through the center of the bottom frame, so it should be a good bit stiffer than V1. Based on the material volumes the slicer tells me, it should weigh about 5.76g for the bottom only. I can probably cut some more weight by reducing the wall thicknesses in the middle, I had to extend them outwards to get carbon around the holes and I was too lazy to thin the inside out at the moment.
I just revised it again to cut some weight out of the center of the frame, v3 should now come in at about 5.1g.
The top has also been modified to path fiber. V1 only puts it around the perimeter which is good enough, really. It's the 13 degree top for fast forward flight, haven't made any of the other angles.
Once we get Onyx (new Markforged material, nylon with chopped fiber) I will try a print in that with continuous carbon as well, that should be plenty strong and stiff for any application.
If anyone wants one of these printed and doesn't have access to a Mark Two, I can probably print some. It might be a bit more expensive than if it were my personal printer, but I'm sure I can help some people out if needed. You could probably get away with just using my lower frame with a standard ABS upper, that part doesn't really break much in the first place.
I plan on printing v3 frame in the next couple days. I've extensively crashed v1 over the past few days and it's tough as nails.
Update: I've printed the v3 frame with Onyx (chopped carbon in nylon) and also have CFF strands of carbon fiber in the part. It's super strong and still crashproof! Check out the photo of the bottom frame with a 8lb granite block on it, there's barely any deflection. Very impressive strength from a five gram part. The combined frame weighs 7.5g and my quad weighs 38.5g without a battery.
