1m long Omega Class Destroyer from Babylon 5

I’d love one of these, though must admit that a 60-70cm one would be sweetest. Do you intend to upload for sale via Shapeways or similar or keep it as ‘home production’?

Cheers

I'm still tweaking the 50cm version (actually about 58cm) so that ones not quite ready yet. Its not as easy as just scaling the model by 60% as many of the details, part sizes, screw holes etc dont work when doing that. Plus some of the way the big one has been broken down was because of the printer size, so in smaller scale i can combine some parts. I think its nearly ready though, another couple of weeks before im happy with it i think.

I'll print them myself, i looked at shapeways, but to print just the rotating section would be $1456!!!!!!!!

So a few people have asked if i'm going to kit this ship, and the answer is yes :D
In fact a while ago another RPF member who happens to live near me contacted me and asked for one, and it finished printing today.
Ended up being 3312gm of plastic, and 283 hours and 24 mins of printing!

For scale, each bag in the pic below is 22x25cm.

Just received my last night and I only have one thing to say "It is a killer" if you a Babylon 5 kit collector / Builder it is a must have for your collection.

Watch out for my build review in the next few months.

Of course now the pressure is on me to finish mine first :D
 
I've used modified servo's on my Jupiter 2 and a Model RR turntable, and it's not resistors that need to be changed, its the "Stop" built into the gear mechanics. Just cut off the stop, and use the power connections, bypassing the servo circuit. You'll want to remove the resistor/brush thing that the curcuit used to detect position of the servo too.

For me, I always wanted a BIG Minbari "Angelfish ship. I acquired a pirate Shadow Battle Crab back in the late 1990's which I made molds of the body sections. I used brass wire with tinfoil wrapped around for those skinny 'fingers'. I covered them in black glitter so as they moved, it looked like the surface was moving.

Theres more than one way to do it. With your way, you're essentially using the servo electronics as just a speed controller for the servo motor, which will work just fine. I may end up going that way, or just using one of those little 3v geared motors.

The rotating section is now built and ready for paint!
I havent put in the rotation motor yet, but the end panels are screwed on, so can be removed when thats assembled and ready to go in.
Also waiting on some LEDs to arrive before installing lighting, but since this section only has 12 points of light in it, and holes for most already exist, that will just drop in when ready.


I love seeing the result of all the mouse clicks to design it, in front of me in physical form!

Work is still progressing on the ship, have been in the sand/putty/prime/sand/putty/prime/sand/putty/prime... phase lately.
The engine section is just about ready, all the detailing is added, and finished smoothing the engine tubes today. Have a last bit of sanding to do on the aft section and it will be ready, then just some work on the head to do.


I have started painting the side detail panels though (the ones where the red missile tubes are) since they just slot in, so i can do them and just drop them in when ready. Am doing some colour testing deciding exactly what colours to use.
In the show it looks quite shiny, with metallic silvers, gun metals, and metallic grey colours, but i think thats more to do with the CGI rendering. To me it should be more matte than shiny, and probably varying shades of grey (light and dark). But i may use some gun metal in a few places so will see how i go.

Also, you may have seen it mentioned that I have already printed a second one for someone else. They've been flying through it and provided feedback. I made a couple of tiny tweaks to improve fit on a couple of parts, but besides that, it looks like the design is done. Have also finished the instructions and a doco with construction and printing notes. I printed it for Muzza who has posted in this thread so you can ask him what he thinks of it.


That means for those who were interested in buying a copy of the printable files, they're now ready!
Am asking $100US.


PM me if interested.

Feed back...........It is fantastic and I will be buying another one so I can have two flying around the house.
 
So I havent done much on the Omega for a few weeks, started a new job and havent had a lot of spare time. But i put today down as a day to work on it, and got some good progress. Decided i'd spend the day getting the rotation and power to the rotating section working.

Did some checking of clips from the show and it looks like it rotates somewhere around 1-2rpm. To get something that spins that slow, with enough torque, i ended up just using a continuous rotation servo. The speed can be varied so I can tweak it if needed. Originally i was going to try and mount the servo on the centre supporting aluminium tube, but it was a really tight fit and i wasnt happy with it. Instead I mounted the servo in the rotating section, so it drives against a gear fixed to the centre rod. The servo has about 3-4kg of torque, but i've also got it geared down roughly 7:1 so gives plenty. Also fitted it with a small DC-DC step down converter to supply 6V to the servo, and to an Arduino to drive the servo.

As well as that, i made up the power rings to get power into the rotating section for LEDs etc. I got a copper plumbing fitting cut down to get 2 rings, mounted on a plastic tube to insulate from the centre tube, and mounted that in front of the main gear. Gives power to the arduino/servo, and for LEDs as well. I'll also use the arduino to flash some LEDs. The 2 brass contacts havent been bent to their final shape yet, but they're held under spring tension so should keep good contact. Also put on a smear of carbon grease to keep it moving nicely.

Wow this is looking good. Getting ready to rolling if you pardon the pun.

Wow, that is coming along very nicely.
I was on the lookout for a WARP Omega (until I found this at least) and was planning on doing the same for the rotating section. I even bought some sliprings for it, which is essentially what you made from scratch. Just a warning, if you do a search for "Slip Ring" in eBay... make sure there are no children present, or you may have some explaining to do for some of the less electrical oriented entries. :)

I did think about a slip ring, but given the size, and that i have a 16mm aluminium tube running down the middle for rigidity, a slip ring wasnt suitable. I'd have to break the centre rod into sections which would ruin the rigidity.

The copper plumbing fitting cost me about a dollar, and the brass strips were in my parts box, so basically cost me SFA. I do need to give the copper a bit of a polish though, bit rough at the moment.
 
I love this Kingbob, really impressive. Someone shared a model they got off you on fb in the Babylon 5 fan page.
I've just recently bought the Warp models kit, but if I had seen this first.
I may in the future consider purchasing the files off you to 3d print. Though I don't have a printer myself yet my dad has recently bought a couple himself.
If I could ask what is the printing area required for the largest sections?

Simply amazing.

Best Regards,

Wolfe.
