Re: 3d Printed Rocket for D and E Motors

Yesterday this rocket had its maiden flight at NSWRA's launch. As you can see it had some good company on the launch pad. https://i.ibb.co/nRb2Td6/IMG-9086.jpg It went up nice and straight on a D12-3 https://i.ibb.co/qgxMKLY/DSC0764.jpg The chute deployed right at apogee, but it appears the nose con...

Re: Thunderbird 3 Build

A nice snug fit on the body tube. Fin alignment should be a piece of cake with these cut outs. https://i.ibb.co/fSYqXMq/ih-DHJxe-RREy-C8fgy-Rk09hw-thumb-4ae3.jpg Because the sleeve was a 16 hour print I first printed this test piece to check the fit. https://i.ibb.co/PsLG2CB/TSd-Pac7g-Qq-GQr-KN6-Y81...

Re: Thunderbird 3 Build

Looks real nice, any tips for post processing 3D printed material? No tips unfortunately. I wish I had some clever ideas, but I think it will just be good old fashioned sanding and then a few coats of filler primer. I like this stuff from Super Cheap Auto: https://i.ibb.co/q0zhqJf/SCA-288527-hi-res...

Re: Thunderbird 3 Build

I printed the aft sleeve. This was my first time printing PETG filament, so I am very pleased with the result. https://i.ibb.co/FXnZQ4X/IMG-9052.jpg The definition and detail is excellent and the layers are barely visible. After a light sand and a little filler primer it should be fine.

Re: Carbon dioxide cartridge rockets

Love the video.

Never seen anyone attach a camera to a small water rocket, but you got some good footage.

Keep up the good work.

Re: Thunderbird 3 Build

The middle section of the rocket needs a lot of cooling fins and I didn't want to glue these on individually. So I decided to design a 3d printed sleeve, with the fins already attached. This sleeve will be glued over the body tube. The idea being that the cardboard tube provides most of the strength...

Thanks Jim. Good point.

I should have pointed out that i will be using a more traditional method of propulsion.

Re: Thunderbird 3 Build

It wasn't easy deciding how big to build this, but in the end it came down to availability of body tubes. The rocket can be broken down into 3 body tubes: - Aft BT is the largest and has the boosters attached. - Mid BT has the cooling fins attached. - Fore BT has the docking ring and the booster arm...

Thunderbird 3 Build

I have been planning this build in my head for several years and I have decided 2020 is the year I'll finally get it built. I have collected a stack of reference material, but much of it is contradictory, so building a faithful scale replica is tricky. But I hope that mine will at least be instantly...

Re: 3d Printed Rocket for D and E Motors

Really awesome. I like post with all close up photos of the parts and the designs. I have a few questions... * What filament did you use? ABS plastic? * What sort of fill did you use? 15% or more? * Any other (non-default) settings set for the print? I once used 3-D printer to create parts for &quo...
