Hi,
I'm Adrian from Hungary/Europe. Let me introduce my tricopter project.
My goal was to make something really good-looking copter that have ally features I need.The design process started 1 years ago. My first idea was to make a composite chasis, from glass/carbon fiber.I designed the copter in a 3D modelling software, and also designed the necessary moulds for making each parts, here is the initial design:
This is a sample of the mould design:
I also made some FEM calculations, to check the stress dispersion:
Unfortunatelly, this type of production would cost too much for me. I tried to find partners in Hungary, without success. So I almost forgot this project. But some months before I read a lot about 3D printing, and finally I found a great partner in Hungary (many thanks to the Ground Zero Team www.groundzero.hu !!!). So I started to redesign my copter according to the requirements of 3D printing:
Then I sent the .stl files for FDM printing. Here is the result:
This is my current configuration:
- Turnigy SK3-2826-1130 motors
- 8x4,5 karbon SF props
- 10A HK ESC (simonK firmware)
- ArduFlyer 2.5 with ArduCopter 3.0.1 code
- ULOX NEO6-M GPS
- 2000mA 3S lipo (2 db 1000mA 3S2P)
- Flytron 25A ultralight current sensor
- MKS-DS95 servo
- RECOM 5V 1A power supply for electronics
- 3DR 868 MHz telemetry module
- RCTimer OLED screen
- Immersion 600mW 5.8 video TX + Coverleaf antenna
- MinimOSD, with KVTeam code
- KPC-E700PUB camera
- FRSKY Futaba FASST-compatible receiver, PPM
- controlled LED-s and buzzer
All-up weight is 782g, and has 8 minutes of safe flight time with 20-25% of remaining battery.
(Please note that I used Crius AIO Pro at first with MWI code and KV-OSD code. These can be found on the following pictures and in the videos.)
LED sripes are controlled by APM:
Here are some videos:

stl files can be downloaded from here:

And these are the additional metal parts for rear arm control:
I wish you all good luck on reproducing my tri.
Please note that I'll not modify desing according to personal wishes, since my spare time is quite limited and I focus on my personal projects. Thanks for understanding!!!
Best Regards
Adrian

Always amazing us with your projects Adrián, keep up with the great work!
Respect! This is top notch work, putting it out there for the community to enjoy earns you even more credit.
It looks great. Great job!
Adrain, hats off to you for sharing the drawings and STL's top notch. Perhaps if anybody prints one of your designs they might buy you a beer via paypal or some such. It would be the right thing to do.
Do you happen to know if anyone at GroundZero speaks english?
They did not seem to have any english link in their website but I guess that english is spoken everywhere atleast enough to arrange contracts :)
Could ask them if they could serve clients in other European countries too when you contact them next time?
I have tried contacting every Finnish 3D printing company i have found but most of them have not answered and many has on their site that they only serve businesses. Some have answered but they have ridiculous minimum orders or contract fees like 500 euros extra for single run or 2800 euros one time fee for a year and after that you pay "only" for printing and shipping.
These are totally ridiculous amounts in my opinion for individuals or even for some small companies imho.
I know that in states they have companies which just let you upload the files and their system calculates estimation for printing and shipping and then you just pay with you credit card and wait for the print to appear in your doorstep.
Wow what an awesome piece of work it is ! Hats off to you, you have really shown the fruit of your mechanical engineering.
I updated the BLOG with stl files and drawings!
Greg, this type is not waterproof. It has many holes around for air went of cables, etc that sould be removed. Not a big deal but should redesigned. Also FDM printed parts are not waterproof for thin shells, so it should be painted on many layers.
Earl, I'm not sure makerbot could produce these. These closed shapes need highly accurate printing and also many-many support material. For example, center part needed twice amount of support material than model material. If your system can't use support material it is impossible to print these. Although great-looking parts could be printed on makerbot, but with completelly different basic design. Just keep on working on them... ;)
Ok, thank you. I have a 3d printer I can use. It's the makerbot...the wood one. Think it would work. Looks like the parts would fit.
Earl
Now we need someone to make a shell like this for the 3DR Y6 :-)
How much rain do you think these fully enclosed systems can take?
