1/4.5 scale Tomahawk fincans. Scaled for Estes Pro Series II 2" body tube. Not quite a scale match to the PSII Nike Smoke - but a whole lot easier to put electronics in.

Built with VCP's generator and dressed up in Tinkercad. internal channels for 1x10mm carbon fiber flat stock.

Sandia-type fins.

Fins for the 12" payload version that flew X-ray telescopes in the 1970s

and for completeness, a Nike interstage.

The Interstage is mixed scale - it's sized for the PSII Nike Smoke as the booster, and the PSII 2" as the sustainer. Also done with VCP's transition generator and touched up in Tinkercad.
 
My first post on the forum. I'm well into my 3D printing and electronics, spend a lot of time printing random things. Also play around with arduinos and pi's. Though about getting into rocketry as I used to have the Estes kits some 25 years ago.

Looking at integrating my 3D printing and electronics knowledge into a new hobby.

This is something I put together as I have a lot of spare RC parts laying around from my drone building days. Plan to install 2 sg90 servos into this body section and control 2 fins using arduino.

I know it must have been done numerous times already but just thought I'd give it a try myself.

bps.space uses a highly similar concept to gimbal the motor itself -- would be interesting to see both concepts combined although I imagine the control loop would be tricky.

I've also proposed a wiggling nose to go with the steerable tail, but I don't think anybody's tried that yet either.

I suppose you could also hula a fincan for a similar effect, though less usefully.
 
Last night while clearing out some old drone parts in found a couple of old CC3D flight computers that were heading for the scrap bin. As these give auto level for drones I plan on testi
 
Testing them out with a couple of servos. At the same time printing out the part I threw together on tinkercad. Have a few fin designs I've found on line I'm gonna print also.

It looks like the link isn't working. Thanks.
 
I finally got around to uploading my "Example Rocket" to Thingiverse. It is a simple rocket that I designed for a presentation on 3D printing. I attached a shortened version of the presentation to this post, with the full version included in the Thingiverse download.

I posted up a number of rocket related files in Thingiverse. here is a snapshot:

1) Mobius Action cam rocket mount: (from 2013)

2) Saturn V launch Tower

This was also posted in 2013 and it's a specific replacement for my 10" polecat. Need a BIG printer to print it unless you want to cut it into pieces - at least 400mm Z height. I also uploaded the sketchup file if you want to modify it. https://www.thingiverse.com/thing:104604

3) 38mm motor high powered rocket parts

Uploaded in 2014 - fincans and nosecone's for 54mm tubes. Actually flown this several times. Still have the autocad files if anyone wants them.

I now post more often on myminifactory.com as I like their laze-fair policies more.
Alex, what is your username at myminifactory?

Hi Greg,

Sorry, I bolted from myminifactory. New management kept trying to get me to monetize my files, grow my 'fan base' and become an 'influencer'. Constantly sending me irrelevant tracking statistics. I'm starting to miss internet 1.0 where I could just FTP an entire directory. Thingiverse sucks, but at least they aren't trying to be Instagram.

The second one of the Kardashians get a 3d printer, we are all doomed.....
 
Long time to posting (life gets in the way...) had some time off recently and finally got around to learning a little about Fusion 360 and designed a shroud for my Runcam 2 on my 4" Deadpool Rocket:

https://www.thingiverse.com/thing:4110894

*** images snipped ***

@snrkl this is a great design. I've been looking for a shroud for the RunCam 2 for awhile now. This is going to work well on a pair of in-process Apogee Level-2s for myself and a friend. Printing one now. Thank you for contributing this. Well done!
 
My OpenSCAD configurable components are buried on a thread that people may miss, so I thought it would be a good idea to put links to them here in the 'repository'.

All of these items are OpenSCAD language files that are used with the OpenSCAD CAD program. Knowledge of the language or use of the CAD system is not necessary - all of the files use the OpenSCAD Customizer feature, which places configurable parameters in a (somewhat) easy to use set of controls and entry fields. The user must, however, install OpenSCAD and do some minor configuration to use the Customizer. All of this is detailed pretty clearly (I think) in the first item.

In several cases, I've included the original item post, which contains instructions and screenshots of the item, and a follow-up post with updated code. In all cases, the code is in the form of a downloadable .txt file, which must be renamed to .scad for use by OpenSCAD. All of the files can be opened in a text editor, and they usually contain OpenSCAD install instructions in the comments, plus instructions for use of the item.

After I go through and clean these up, I'll eventually get them all on Thingiverse. Enjoy.

CONFIGURABLE FIN CAN << This first post details OpenSCAD installation and use, and instructions for use of the Fin Can. The OpenSCAD file is updated in a follow-up post here.

TRANSITION SECTION GENERATOR

CONFIGURABLE TRAPEZOIDAL FIN CAN

CONFIGURABLE CENTERING / CLUSTER RING GENERATOR

CONFIGURABLE FIN GUIDE

CONFIGURABLE TUBE DRILL GUIDE

CONFIGURABLE RAIL BUTTON STANDOFFS... but this was replaced by...
CONFIGURABLE AERODYNAMIC RAIL BUTTON STANDOFFS with updated code here.

CONFIGURABLE INTERIOR RAIL BUTTON NUT BACKPLATES with updated code here.

Gee, I didn't realize there were that many. I really need to work on some more.
Any chance for an insertable configurable fin can instead of a sleeve type?
 
Cross posted from my Spudnik build thread

Problem ... Estes launch controller requires two hands to operate, and I can't hold my phone and make video at the same time. Designed and printed a sleeve for the controller with a couple of ears on it for rubber bands to hold my phone.

PROBLEM SOLVED
First ... I cut about 1/8" off the rubber sleeve on the pin. Still need to hold it down, but doesn't require near as much pressure now.
Next I hit Tinkercad and designed a phone holder for my controller. It just goes over the end, and rubber band holds the phone in place. Neat.
Put the holder on the controller, put a rubber band over the phone, and voila! hands free recording, and both thumbs can operate the safety key and launch button.
Now I just have to go to the $1 store and get some real rubber bands. You can see I only have little wimpy ones.
It could use a few tweaks, but it works as is.

My design for a tray to hold the Loki 38mm 120, 240 and 480 motor casings. I have the OpenSCAD file for it, but can't post that, as .scad is not an allowed file type. Therefore, download the file Loki_38mm_120-240-480_Hardware_Tray.txt and rename it.
