3d Printed Nose Cone Camera Mounts

Postby Aquaman33 » Wed May 08, 2019 11:27 am

I was really impressed by these Swinger/Flipper nose cones so I thought I would share.

I first saw them on Video Rocketry's Facebook page
https://www.facebook.com/VideoRocketry

You can download the designs for free from Thingiverse:

They are designed to work with 808 video cameras and BT-50 body tubes.

The nose cones allow the camera to "flip" so that you can film facing towards the ground before and after the chute deploys. This is something that can easily be achieved with a camera mounted on the body tube, but these designs allow you to get the camera weight forward.

Really cool idea for people that want to get into video with low power rockets.

Will be interesting to see slow motion shots as the nose cone blows off and the chute deploys.

Definitely on my list of projects for this year.

Is there anyone out there with experience of 3d printing nose cones?

I am wondering what level of infill is appropriate?

I am printing this one with 30% infill and 1mm skin. Seems like it will be strong enough but not too heavy, but I am just guessing to be honest.

Image

Not sure why it printed those supports on the outside. They don't seem to add any strength to the print and stop short of the shoulder, which is weird.

The engineering definition is for a part to be fit for purpose. If it survives what you want it to then it is at least as strong as it needs to be :) . One advantage of 3D printing is that you just press "Print" again if you break a part.

I have done 3" and 4" nosecones for my Nike Apache. They are 3mm thick and printed in ABS with no infill. There were strengthening ribs added to the 4" version.

Don't forget to allow for the z-axis weakness when working out how much material you have to use.

Thanks OverTheTop. Your designs are amazing.

I too did some experimenting with 3d printed fin cores, but decided against it in the end.

Finished print. Came out almost perfect first time.

Image

The designer suggests using a piece of 3d printing filament as an axle. I think a paperclip will be stronger/safer, but I used a piece of styrene rod for now.

Image

The base needed a little sanding to remove the print grooves and then it fitted perfectly.

Image

Image

Image

Image

Image

The nose cone that came in this kit weighed 21.4g.

Image

The 3d printed nose cone weighs 31g without the camera.

Image

And 49.8g with the camera.

Image

So I have added 28.4g to the rocket, which isn't too bad.

I think you could shave off another 5 to 10g if you printed it with less infill.

Looked forward to testing it out.

Thanks to Video Rocketry for sharing this design.

Very interesting design. I look forward to seeing the results you get with it.

Thanks George. It should be interesting. I may swing around a lot in the wind and make horrible videos. We will see.

I printed the BT60 version. I then realised that all my BT60 rockets have 18mm motors mounts. With the extra weight of the camera I think this will need a 24mm motor, so time to build a new rocket!!
