3D Printed parts

by tophe75 | August 11, 2013 | (11) Posted in Projects

As I just got hold of a 3D printer, I thought, why not try to print a few FT parts like the control horn, swappable firewall and more.

The thing that got me started printing R/C parts was this: http://www.thingiverse.com/thing:97357
The problem was my print did not fit that good, so in Thinkercad I did a remix of the part that is more to my likeing.

This is the result:


Next the control horns. First I did a "copy" of the lasercut ply once, but as I am cheep, I made them light weight.


Just as that was done, FT released the FT Versa Wing. I had to build one.
I wanted a pusher but I did not have the FT Elements Simple Firewall.

Let's print one!

Used Thinkercad to do the CAD file, after some post print clean up and some trimming (my printer is not that accurate) the pices fitted and glued with epoxy.



Also, I did not want to use the "straw" solution for the pushrods (or zip ties), so I printed two Pushrod Guides.


The last part I made was an "Electronics Rail" for the FT Versa Wing. It's just a rail to mount tha ESC and the RX on, but it works and is glued to the wing so that the ESC and RX can be replased in no time.


So, to sum it up.

Yes 3D printed parts works great.

And to keep up with the FT spirit, all my parts are free and can by found @ Thingiverse: http://www.thingiverse.com/tophe75/collections/ft-parts I will add more parts as I make them.

I hope you will like it.

And for the once that stayed this far, a bonus video:

That is going far above and beyond. Great job! How durable is it compared to ply parts?

I have not don first flight yet, but my guess is that it is more durable then the ply.
Will post back after my FT Versa Wing fight (motor used is a 3530/14 1100kv) so...

You should also do the anycopter and the copter landing gear also. This would be helpful as I had a friend with a 3d printer so I could just run to him and get hem made.

As I don't have an Anycopter, I will not make parts for it, as I can't verify the end result.
I will only share designes that I am happy with (that is the reason that the FT Elements Simple Firewall is not made public yet).

got it, i just figured that you could go and get the pattern, do your thing with it and post it, but i understand your point of view.

Someone else uploaded the FT Elements Simple Firewall to Thingiverse:

I have added it to my collection so it will be easy to find.

My "onepice" FT Elements Simple Firewall has been test printed and added to the collection.

From one CAD man to another, Great work!
I hope to have my own 3D printer someday, Have a nice flight.

Thank you, as I know nothing about CAD, I am glad you like it.
This is the printer I am using: http://reprappro.com/products/mono-mendel/
One of the cheepest out there.

How does the weight compare with plywood?

I don't have an accurate scale to see the different, booth are under 1g, but my guess is that the plastic one is the heavier one but my feeling is that the lightened plastic horn is the same.
It is a guess...

My neighbour flies FPV multirotors for his job and recently bought a 3D printer to print out mounts and other parts for the multirotors, the printer is very useful for that sort of thing.

Good work. I think we'd all like to have laser cutting equipment to make stuff like flitetest does. But 3D printers are way cheaper (you need a descent wattage laser for cutting plastic etc. The cheap ebay ones are way to under powered).

How much does it cost in plastic to print these things?

Not sure.
One spool costs (in Sweden) about $60 and is 1 kg and one control horn is under 1 gram.
The firewall is 5 grams (laser-cut from FT is 4 grams)

So the cost is not that high.

But I just love to be able to make stuff for my self.

You should make this into a business.

Nice job, it's funny because I had done the same thing but I printed the plans and then pulled all the measurements off of the plans and redrew them in librecad. Works great, printed them out in nylon. I was actually going to make some control horns and that's how I found your post. I am actually doing a remix on David's tricopter design, I took David's original tricopter frame dxf file and took all the curves out and made hard angles . Also took the camera tray PDF and converted it into a dxf file to be used in librecad. I laid everything out so I could set them up in openscad and use the extrude function to make 3d models and export as stl files. I have all the stl files ready to print but I need to rebuild my x axis as it is cracked and falling apart.(very bad warping from my abs parts I bought off ebay finally gave out). I will do a write up and put some files online when I get a chance. Good job though and I am glad I am not the only person trying to do this. I have already have printed and am using tricopter v2.5 right now. Works great thanks David.

What program do you use to make the models?

I started out with SketchUp but for the simple designs I am doing I found Tincercad to be easier.

Have you flown this since 2013???
These are some clever solutions! I'm anxious to see how they work, and last.

Yes, two weeks ago. An FT Arrow with 3d printed parts. Also fly a lot of Quad worth 3d printed parts as well.
