Getting back to Gort. I designed a visor that rotates. I'm not sure how to get the visor to open slowly like in the movie. I don't want it to get too complicated with Arduino programming and servos just to get a basic movement.

I'm also debating not cutting holes in the bottom of the chin, as well as making an inner helmet like the filming prop had, since this will, most likely, be sitting on a shelf, but I think it would be kind of ominous to have the visor slowly open, and then an LED (or series of LEDs) would come on and gradually brighten behind a translucent inner shield.

Can you get planetary gear sets off the shelf? Those are simple and compact and allow big speed changes.

Also a worm and wheel will reduce input speed a lot.

 

[laellee]

That's what I was thinking.

I think the issue is finding a servo that is already limited to perhaps a 90 degree swing and can automatically limits it's movement; so positive voltage applied swings 90 degrees and stops, reverse the polarity and it swings back and stops. No arduino, no dealing with controllers for the servo, just a simple 3-way. Linear actuators can get the job done, but then the speed control goes out the window.

 

[ID10T]

DC motor with a worm on it driving a large diameter ring gear will provide what you want (and lots of torque). Reverse polarity to go the other way.

Limit switches on each end cut power until restored to travel the opposite way... Easy to do without any electronics at all. A 3V DC motor and a 321 battery would do it.

ID10T and laellee , thanks for the really great ideas. There are some solutions out there, with inline servo speed controllers, for RC aircraft flaps, that I looked at, but that movement was still way too fast. I estimated that the Gort visor should move from open to closed in about 6 seconds.

I should have mentioned, that I needed an almost off the shelf solution, that even a relatively newb could implement, but it got me thinking about a past project that I had (uncompleted, of course), where I wanted to use a miniature gear motor. All that someone would have to do, is to mount a disc onto the gear motor and create a linkage to the arms of the visor. I calculated that 10rpm would be adequate. The movement would be cyclic, but at that slow RPM it would be easy to start and stop it with a button push. Plus if the piano wire linkage was thin enough, the wire would bend once reaching the visor closed position and keep it closed for a second or two.

Or that if the servo/RC flaps doesn't work

I have spent the last three months attempting to understand 3-D modeling software and it makes absolutely no sense to me. I don't understand why they can't just make a simple program where I can import and existing STL and use simple shape to create a new one

I'm building a 3-D printed Battlestar Galactica and while the model has space for lighting the engines, it doesn't actually have any pieces to facilitate it, I'm just trying to create essentially a circle with a base that has holes for the LED wires. i've got a really cool FX board that is going to re-create the flickering

I have no idea why I find 3-D modeling so hard, but I have for the 20 years I've tried to do it off and on it just doesn't make any sense to me where having something I can hold does. I know what I want to make, I just never have the ability to realize it

Is anyone willing to help me? I'm also very impressed with the APC above. I have one of those in progress as well, but I don't have any chairs or figures for it because they haven't made them in a very long time. I finally found some helicopter pilots that I can modify to fit the dropship but I'd rather have the real thing

What APC or dropship are you talking about? I'm not certain your are in the correct thread. This thread is for artists who have created 3D designs and not for persons who have purchased 3D designs and are printing them or want to modify other artists designs. Requests for services should be in the Want to Buy forum.

i'm asking for help developing my 3-D modeling skills or creating the part that I need, and I figured a thread full of people who are making 3-D things would be a good place to find them.

i'm not modifying a design, I am creating a holder for LEDs that is holy original and not modifying anyone else's stuff. I was merely saying I could provide the STL so that people knew what they were trying to fit it into

When you mentioned the "APC above" when there was no APC, (along with a "dropship) I figured you were looking at another thread, and mistakenly replied to this one. If you quoted a post, it would have given ideas to members what you were talking about.

So you're looking to make an add-on part to a 3d model you're printing. What problems are you having? What software are you using?

Totally get it. I have fallen across a few threads here in rpf land that are aligned with that exact thought process but you have to catch them before everyone has wandered off, elsewhere. Jintosh has one that is a repository for personally made stuff that you can also download and print and often the folks there are using varying softwares and offer advice and help with random features. Usually, the ones that are the most helpful are those related to your prop source, like if it is from Battlestar Galactica and there is a ship thread for that show, there will be many modelers all interested in pushing out the pieces like your LED holder. I haven't yet seen one that is 3d modeling shared training like a thingiverse thread or Fusion 360 thread but maybe my search skills aren't the greatest. This one is a show off thread so is usually pics from folks who are more the post and wander away group. Shy, skilled, and looking for pretty pictures of inspiring projects but not so much watching the thread for convo.

So my offering (keep in mind, I am a degree holding engineer and HATE 3D software) is the

Prop Replica STL files Section Free Personal Use

There's no Official place on TheRPF.com website for Free STL files, but I'm starting a thread for them. The files in this thread are for personal use only. Do NOT repost these files to other sites. Each post will include a basic STL file (ZIPPED and under 10mb) and a rendering of the product...

www.therpf.com

Does anyone else have some good thread pics or possibly outside sources with live AND understandable training forums?

Bickle2 if you post your 3d sofware name we can probably find a much more precise answer.

Let me make sure I inderstand the ask, you are looking for a feature, within yours, or in general all 3d software that will "fit lock" the outside of your LED holder in a current stl model of a specific ship and you already have the ship stl. Like clicking on the face of the windows internal frame, lets say porthole, and get that to create the matching outside frame of the holder? Like a possible: click, choose specific face only of current selection, copy, save as new project (but a hair smaller for fit) and close the face into a printable 3d object ( with a thickness ) and then assign the hole size for the LED?

Several years ago when I got my first printer, I downloaded a poor model from Thingiverse. I made a couple of improvements but it wasn't the correct size in the first place and my 3d created improvements didn't make it look much better.

There are several 1995 Lawgivers out there, some pretty accurate, but I wanted to create my own. It is hollow and can accommodate electronics and LEDs.
