A friend needed a Dagger (actually 4 of them) for cosplay at an upcoming anime convention.

This is my first dagger, so I'm not sure the best way to go about printing such a thing. He seemed pleased with the result though, so that's what counts..

I am slowly assimilating my RCExplorer.se / David Windestål tricopter into a 3D printed version.

His design is heavy on zipties, but where I am, I can only find the cheap kind that break before you even tighten them..

I have yet to redesign the tail section or mid body section. I think a mid body section that folds more like a tripod would be cool..

I also plan on adding things like a prop shroud so that if I run the thing into my face again, it will cause less damage. :D

A friend had been wanting a Grenade. I had seen a few designs already, and really liked some, but wanted to add some additional functionality.

Not to completely reinvent the wheel, I incorporated a few of those designs and made the thing modular.

After many Boolean operations, and due to poor planning, I accidentally created a locking feature with a ridge on the opening of the grenade body.

I got griped at for taking this into a public place.. I really didn't consider that either..

Maybe I was just lazy, but I didnt want to have to remove the spools from the back of the replicator in order to quickly print another color...

With this this spool holder and some mirroring, one could potentially mount 6+ spools to a replicator.

This design is quite blocky and unrefined. I was in a hurry to add another color..

Having troubles with vibration causing the motors to wobble freakishly.. beefed up the mount and integrated it with the upper half of the vertex and all seems to be better now.. Hooray rapid prototyping!

So I got frustrated by my larger, complete redesign of my arducoper, and instantly fell in love with brucedjones's bodgie design. I also really want to do FPV so I redesigned the way the Aeroquad board mounts to allow for an X configuration. I did this by moving the arm mounting holes out about 1mm, So you can still choose a Plus configuration if you want.

The lower platform was designed extremely quickly as burn out was starting to set in here as well.. A quick GoPro mount was added to this and I had plans to make a quick AV transmitter mount, but booleans and maya weren't cooperating...

I have just rubber banded the RC rx to one of the arms for now, but may look into a more proper way to keep it on.. Maybe an upper cage to protect electronics and constrain wires?...

I have really only flown once so far.. about 3 minutes of hovering around while mosquitoes were trying to eat me..

It oscillates a little with the 1500mah batt and I had a few hops with a 2200 and it was really unstable, so It will need some PID tuning..

FPV electronics and Gopro may make things a bit heave, esp with a 2200mah batt..

Though holding in my hand at about 2/3 throttle I was showing about 10 amps coming out of the battery, which is a bit promising.. between 1/2 to 2/3 throttle seemed to be about hover position.. again only one flight and distractions..

I got different motors for my bodgie incarnation, so I designed some different arms to mount them on..

It seems common place to use nylon/plastic screws on quad/multi-copter builds.. Which I don't have an abundance of.. which got me thinking about alternatives: the zip-tie, cheap, easily available, gotta be fairly strong right?

Well it turns out I don't have an abundance of 2mm screws either.. Short story shorter, this is an experiment in using zip-ties to mount small quad-copter motors. I have also designed an arm with holes to mount the motors with screws, but have not printed it..

So I purchased an Arducopter Pre-assembled and tested, Something I rarely do. Maybe it was a subconscious action then, that within a week I had smashed it into the ground?

Now I am designing and rebuilding it, testing and learning and really enjoying it.

Some pieces survived and I had initially thought to design things as a replacement/upgrade. Now I think that would be silly to tell people to "Print these, and buy these 'special' parts", so I am making the attempt to make this frame fully DIY...

I haven't really been documenting the process, but initially it seemed there would be a slight weight savings in the carbon fiber/ABS parts vs the stock arducopter aluminum/acrylic parts.

Maybe some different construction methods could be used to increase savings?

This is very much a work in progress, but thought I'd get the idea out in order get some feedback and enable collaboration.

I recently wrecked my arducopter and am now trying to redesign/rebuild it. I modeled this piece in maya, using my own measurements, so it is not exact to the original, but should work just fine.

Thinking of a general cellphone/smartphone holder, though may be useful for other things..

Untested, A quick change to TimeLapse CamHolder
( thingiverse.com/thing:9926 )
to make it adjustable/modular.
