Minimum Diameter 3d Printed Fin Cans

Postby Aquaman33 » Thu Sep 24, 2020 9:50 pm

Inspired by Strud's post about lack of posts recently I thought would share some poor quality pics of my recent experiments with 3d printed minimum diameter fin cans.

Having finished my L2 project I decided the go back to low power. I haven't made many minimum diameter rockets before so I started work in Fusion 360.

Starting with a simple 24mm 3 fin design.

Next was a 18mm 4 fin design.

And a 24mm ring fin design.

I woke up to find this on the printer one morning. But it came out fine on the second attempt.

Image

And then there is this thing. Inspired by the Flying Flea and the Mosquito.

They were all fun builds and really simple to put together.

These look great . I have ordered my first 3d printer and hope to see it arrive early next with this kind of thing in mind. Cant wait to see what it can do.

Great to hear.

There are lots of interesting 3d printable rockets and accessories available online, but I think it's more fun to design your own. So worth learning a design package if you don't already use one.

With these designs you just need to buy a pack of body tubes, then assembly is not much more than epoxying on the fin can and then sorting out motor retention and a chute attachment point.

Look forward to seeing your results.
