OLD school 3d printed tricopter.
It was my first 3d printing project back in 2013. (on my replicator 2x)
Some of the STL were generated on a 1/10 scale. you will need to scale them ten time bigger.
Sometimes you gotta run before you can walk
It's design to work with an APM 2.5 (tight in space but it fit in)
I Have fly and crash this frame so many time without any major damage.
I plan to add upgrade if you people ask them.
You can leave your question in the comment section .
Have a nice day.
you only need 6-32 threaded screw and nut.
100 - 80 % infill recommended
layer between .15 mm and .3 mm.
All support structure are in the STL file.
You should be able to remove it only by hand.
It was design to be made with ABS plastic.
General advice from my little experience with abs plastic.
Test all part by prying them a little bit. If you hear a little brittle sound dip the part 1 sec in an acetone bowl and let it dry 24 hour. you can also use a brush to gently cover the part with acetone ( be quick or your brush will stick.)
