Carbon Tube Motor Mount

Carbon Tube Motor Mount by MikeyB Feb 24, 2013

Description

This is a printable motor mount for a carbon fibre tube that can be used on my printed quad or any other multi rotor. Choose from list of sizes. All sizes are outer diameter of CF tube.

Update 7/3/13: I've added the sketchup file for the motor mounts and the spacers.

Update 5/12/13: This project kinda fell to the back burner for a bit. I have uploaded 8 new files for motor mounts. There are two styles, round and teardrop. There are also 4 different types depending on your needs. Unfortunately there is just the 9/16th diameter at the moment. Now that I have the designs finalized I will begin to add other common arm diameters. Stay tuned.

Sorry for the delay. Sketchup file has been posted, enjoy!

Could you post source code?

Thanks!

Sorry for the long reply. Yes the carbon tubes are just clamped between the two spacers. The two spacers together are slightly off of a full circle so that they can clamp the tube firmly. I will upload the .SKP file for this thing soon.

Instructions

Print at 100% infill for the "Clamp" style mount and use 6/32 hardware to secure to carbon fibre tube. Do not over tighten. The other mounts can be printed at 50%. You can either use a 6/32 as a set screw or a few drops of super glue.

Hi,

Great designs, I love them ! But I got some questions:

-What is the total weight of this frame? (exlcuding drive or electronics)
-What diameter of carbon tube do you recommend ? (to be strong enough)

-Is it possbile to upload other STL files of the main body of this frame (in general: just this carbon version). I'm also looking to build one and maybe make a derivate

Thanks a lot!

Thank you! I'm not sure what the "empty" weight of the frame is. I will go use the postal scale at my office and get you an exact weight a little later. I can tell you however that it is lighter than the frame with printed arms (which is pretty light to begin with, 450g or so)

I recommend using 9/16 carbon tubes. The are incredibly strong. I plan on adding files for other size arms but I just haven't got around to it... Stupid job. I will upload the sketchup file in the meantime so anyone who wants to make a derivative will be able to play around with it (the quad sketchup file has been posted to my quadcopter page).

As far as the main body frame goes you can get that .stl from my quadcopter page. The top and bottom plates as well as the top cover are designed to be interchangeable for either printed arms or carbon tube arms.

used wooden dowels wrapped in electrical tape. works really really well.

thanks for this design, im using it and the spacers with your fpv quad. I like the fact that it allows the arms to be any length you like! hell, im sure you could change length in the field if you were so inclined.

Right now I only have the 9/16th up. What size are you looking for? Let me know and I'll get it up.

Thanks! I'm looking for 8mm and 10mm.
Nice design btw. Printed a copy of the 16mm to get a feel for it.
Very strong.

Where's all the sizes?
I find only the 916 file stl with single size?
