Fiain Ros Wren Helmet WiP
« on: Dec 11, 2017, 06:21 PM »
Hi.  This is my first build. I 3D printed my helmet in ABS using a pattern I purchased.  My Mando is a Wren clan -style, so I am using the Sabine-style helmet.

My sketches are not worth showing to anybody, so here's what I've got done so far:

Printing (11/24/17):


All the pieces printed, except rangefinder (11/26/17):


Putting the pieces together to be sure nothing is a problem (11/26/17):
Front


Top


Back


After gluing all the pieces together (12/01/17):
Back


Front


After first seam filling and an acetone vapor bath for initial smoothing - the bottom got nice and smooth and shiny! (12/09/17):
Back


Front



Ear caps have been glued on. When putting together the backpiece and smoothing it, I caused an issue, so I need to reprint that piece.

Question: Do I need a rangefinder? I didn't print it yet. I can, but I need to know so I can finish putting the Helmet together prior to painting.

Thank you! The helmet is coming along. I've decided to forgo the rangefinder.

Here are some photos from a few days ago after I did more seam fills and sanding. (12/13/17)



I've been working on it quite a bit the past few days after these photos were taken and I'm ready to start the priming process. I'm a little random in the timing of my photos.

Update 12/17/17: When you say you're ready for the next step, and then you decide you're going to fix something that is okay but can be improved. Which now means you're a few steps away from the next step.

After more work, I'm at the point where I'm trying to decide whether to keep at those couple of spots that aren't quite right or move onto the next steps of priming and sanding over and over again that may or may not take care of those spots. And if not, those spots could just become battle damage with some weathering.

Photos taken 12/19/17, no additional work done on 12/20.



If you are looking at it in the photos and see something egregious, let me know and I'll try to fix it more. I have one spot on the back ridge that I've fixed multiple times and every time during sanding the divet returns. Thinking I need to just weather that spot.

Honestly it looks pretty dang good. You could mould it and fix the casts a bit easier than continued fretting with the print. But that’s just how I would do it. Easier to say than do lol

A lot of the issues I was having went away once I got through the prime and sand rounds. I primed and used 0000 steel wool to sand after 4 hours of drying 6 times with at least 48 hours between priming sessions to get what I've decided is the finished primed helmet. My next steps is to get my visor made and installed. After that, I'll paint. I have my planned color scheme and design ready, but visor installation seems like it should happen first. After all of that, I'll put the pads in.

Images are a progression of the view from un-primed 12/19/17 (top left) to finished primed 1/7/18 (bottom right) in all images below. The only reason the black looks different is because the lighting is different. I had varying levels of natural light because it's Seattle and I couldn't always take the photo in the very limited daytime hours that also have a lot of variability in sunlight level.

Left side (as worn):


Right/RF side (not going to do RF - instead will have battle damage):

Question mainly for Bow on this helmet - the way I understand it, if an earcap looks like it should have a RF there should be something there, RF, antenna, etc. Would the indent in the right earcap here fall under that same "rule"?

No and here’s why, if there’s a base for the rf to sit in and a cover to go over the rf stalk the cover must be present whether or not the rf is there. Savvy

As to this helmet it’s good to go in this state the night owl helmet has an interesting rf mount system.

Okay, thanks for the clarification.

Nooooooooo!!!!

After the armor party yesterday where I worked on the visor, when I got home I dropped my helmet on my garage floor.   :o A weak spot cracked (kind of expected), but another rather large crack formed in the primer. It is not cracked all the way through.  :'(

I am going to finish the painting on it. I may be able to cover the crack or do something with it. Maybe no one will notice?  :(

I did the first layer of paint today to see if the crack was going to show, and unfortunately it does. This is just a metal-looking base layer to form all the weathering from. I still have 2 more paint layers (ie, 2 more colors going on top).

I may just 3D print and make another helmet. It doesn't hurt to have a couple helmets hanging around, right? Unfortunately, it takes me 6 weeks to go from nothing to finished helmet working every day (some days are dead days where I'm waiting on drying, etc.)

Meanwhile, this is what the current helmet look likes today:


PS: Thanks Bowfanny and Ran for your kind comments earlier.
PSS: Thanks Mysterious Stranger and Bowfanny for your discussion concerning the rangefinder and ear cap. It's great to know that I'm on the right track for that, at least.

Can't you fill it with bondo and sand it down? As long as it isn't structural.

I'd rather start with a new helmet from scratch.

Your post is helpful because it has me thinking about the repair. Bondo is an obvious choice. But, I'd rather not work with bondo for a primer crack on an abs print. Since it is a crack in the primer, I would want to sand it down to the print through 6 layers of primer, then fill with abs glue if the crack goes that deep (it shouldn't as far as I can tell), go through sanding steps, then re-prime. My attempts at sanding an already primed ABS print resulted in some issues on something else. I'm concerned I'd make the overall helmet worse, not better in the process.

While I work on it from the current step, I may find a solution that requires less backward motion and risk of making problems worse than better.  I have some ideas. One is to see if more layers of paint help (I don't think they will.) Another is to work the crack into weathering.

I'm so sorry you dropped and cracked your helmet.  The crack is really hard to see - for me, at least  :P.  You've done some stellar work on this, though.  Absolutely beautiful.

Have you tried filling the weak spot with abs slurry if it’s an abs print? I’ve snapped 3mm abs plates and welded them back together that way.

Battle damage!!!

Seriously though, have you considered reinforcing it on the inside?

Thanks for the feedback, Havelock, Bowfanny, and Mysterious Stranger. I appreciate the positive support and the ideas for fixes.

The long crack is primer only. There's 6 coats of primer in that spot because it primed up nicely the very first coat. It's not on a seam and it doesn't go through the helmet.  I took a really good look to be sure.  I'm calling it battle damage and going to work with it that way. I think regardless of any reinforcement, that crack would have formed because it's basically where the helmet smacked the concrete.

There is a crack on a weak point that I am not surprised formed. I'm going to reinforce that on the inside with abs slurry. I had done that already there, but obviously not enough. Most of it had been on the exterior and been sanded back down in the process. That crack is pretty small and not as obvious.

Someone else suggested using Citadel's Liquid Green Stuff meant for miniatures. Apparently it's meant to go into tiny crevices and be wiped easily away with minimal sanding and impact. Anybody worked with that's stuff? Might that be an option for the small crack in the weak spot?

Never heard of the stuff, but might not be a bad idea to give it a try.

That’s an expensive fix but it should do the job. Citadel stuff is just spendy as it is. I’d hate to see what a gallon of the stuff would cost lol

That's the beauty of our particular brand of Star Wars costumes. Something goes wrong and its not a "$#%@" moment, its battle damage!

I've run into this cracking problem before with my First Order TK kit, and the fix for hairline cracks I've found works really well it gap filling super glue (I used Zap a Gap) mixed with cornstarch. It makes a thin paste that can fill the tiniest of cracks, sets instantly with a spray of Zip Kicker, and sands down easily. I've also started using that method for gap filling in my miniature 3D prints that consist of multiple parts. It may work out for you.
