First: This build can be followed in detail at: http://dzlsevilgeniuslair.blogspot.dk/
Long time ago I bought all the gear needed to build a small quad. I was really busy at the time so they ended up in a box and was quickly forgotten. The other day they reemerged and rather than just putting them away again i decided to quickly throw them together, at least they could sit on the wall and look cool.
I did not have any frame so i quickly lasered one out of plywood:
My intention was not to build an actually flying model, rather a fancy rack for the gear, so I made it quite small to save space on the wall. After mounting the gear I felt encouraged to take it a bit further so I actually connected everything and took it for at spin.
It actually worked pretty well so I thought that now it is a flying model the arms should be a bit longer and there should be some more features.
Really satisfied with the result both look and flying wice I coulden't stop there and made a camera pod
All in all I am surprices that what started as a quick and dirty jub turned out really well.

Ok here is the raw .dxf file:
Frame20.dxf
@Graham, gogo :)
I have converted the .plt file to a dxf. I can post it here if you want it public otherwise I'll just change it for my own use.
thanks dzlonline! I'm sure I'm going to follow your blog.
@Ruwan, No the assymmetry does not affect the performance. I am sure you could make it any shape and still be fine. On the second model I inverted the bottom lattice because it looks better and make the stiffness a little more uniform.
The laser cutter was around 7800 USD but it is a big industrial machine and it was imported directly from China. I know you can get smaller versions on ebay for way less. If you are interested you can follow my efforts to build one on my blog: http://dzlsevilgeniuslair.blogspot.dk/search/label/LASER
Nicely done. I wish I have a laser cutter. BTW how much was it?
I'm also curious, does lack of symmetry in each arm cause any issues, like vibration? It seems the center of gravity does not lie on the "axis" of each arm.
@Mark, lol
Update: your second quad seems to address that, having the mirror image on the bottom plate. I know this symmetry thing is a minor thing, but I'm learning!
Nicely done! I'm going to buy a laser cutter and tell my wife it's part of my $1,500 mini-quad. Thanks for sharing the design file!
No the frame will twist a little bit. You can control this by the number of connections between the layers.
No do don't have .dxf or .dwg at hand but i am sure you can find a way to convert.
Thanks, I will if I make one, do you have the dxf or dwg file, my ESC's are right under my motors so need to change the plan slightly. Is the frame very stiff, no twist at all?
Here is the frame and camera pod in .hpgl format. If you don't have a laser cutter there are plenty of online services that cut for you.
If you make one please send a picture :)
