I bought a Mk45 from Do3d and they no longer bother to reply to my email questions.

Finally finished the new shoulder bells. Neck is printing now and planning on molding my thigh and calves with the prints sometime next week Just want a little extra strength. Was thinking of creating some sort of garter belt to help keep the thighs up.
LEDs are coming in next week. The new arch reactor is in the mold waiting to be filled.

More progress yesterday. Shoulder bells connected and neck is finished and painted. Also decided to fiberglass the inside of the chest and shoulder straps. Biceps are almost done printing as well.
Unfortunately the arch reactor didnt come out as clear as I expected. Forgot to torch the epoxy to remove the bubbles. Another one is in the mold and curing.
Also, going to have to make a new helmet as my previous one didn't survive he drop test down the basement stairs .
hopefully will have one complete this week and working on a printable helmet hinge system. (Trying to replicate pictures mikesnead post).

Were you able to get do3d to work on the hinge set up? I have a hinge setup that works flawlessly on my MK3 helmet but again the faceplate is different on the two helmets that using that hinge on the MK46 it would catch on the jaw and not open but if you would like pictures of what I have on my old helmet I could get some.

I would definitely like to see what you have. I'm gong to attempt to make one myself with photoshop. If I do I will definatly share. Do3D said they are going also going to discuss it with their developers and see what they can do.

Fits really good. I lined the inside with industrial Velcro felt. Makes it nice and soft on the inside.

Also wanted to share. I've discovered a holy grail to hardening my PLA with no toxic fumes and very nice finish. I used 2 part epoxy diluted in denatured alcohol to almost a water like consistency and lay fiberglass cloth on the inside. Made it solid as a rock. Also tested it on the outside on a failed print ( just the diluted epoxy not fiberglass). The alcohol just absorbs moisture and allows the fiberglass to lay really smooth.

What brand/type is the two part epoxy?

I had some old 3 to 1 epoxy by US compisites but any epoxy would work. I would recommend z-poxy because it's really cheap , easy to mix (1 to 1 mixture) and available at most hobby shops. For example if you mix 30 grams part A and 30 grams part B, then use 30-60 grams of alcohol till it's about a water like consistency. (The fiberglass is only on the inside of the suit). The watered down resin makes the fiberglass lay supper smooth. (Start from the center of the glass first) I would do about 2-3 coats over the fiberglass. Also you can put it on the epoxy by itself on the outside as well. Good thing is you really don't need much epoxy since its diluted.

Yes, it's pretty much just glazing putty, primer, paint, more glazing putty and a little wet sanding during the hi-build primer and 1st coat of paint if needed.
Do you simply sand and primer filler your PLA to remove the print lines ?

I just used industrial strength Velcro.
Just wanted to chime in on the hinge quickly: I have the top part done, but I don't have the servo mount done up yet. Once I get the servo mount figured out I'll post files. I have to resize the through holes in the bottom section (currently using press-fit piece of filament as a makeshift pin). I made the base so that for fit up, it can be press fit into the groove of the faceplate in the forehead (using devildog12's helmet file scaled to 95%). This allows it to roughly stay put while positioning, and should be easy to melt into place. Hopefully will have something to contribute later tonight!
TKCC71, let me know if you'd rather have me make my own post on this so I dont hijack/muck up your build post!
I had a mis-print face shell that I'm using as the test dummy (actual is in paint at the moment). Model of the assembly and actual photo. I'm printing a generic dual servo mount that I found on thingiverse that I will test the fit. So far it's looking a tad wide, but we will see.

I don't mind at all. That looks really nice and I like that thin profile. I made the following but wont be able to test it out until the new helmet is done printing. I would like to print a couple options and see what works best. The servo bracket and hinge I made in the attached photo was done with a micrometer so hopefully it should be spot on. The duo helmet servos I'm using are Tower Pro SG92R's.
