ODST Build

More progress has been made on the attachment system for my backpack, i have used luggage bands to fasten the backpack to my chestplate in addition to three 7kg magnets.

The luggage band attachment points sits in my shoulders underneath a panel that folds up, this is to hide them when i take it off. I also made sure that i can attach my DMR on the side.

This works really well and was able to hold about 3 kg walking around.
so im very happy with how this has turned out so far.

Next up is priming it for paint this weekend. : )
 
Finally priming time!
The way I usually prime foam is by first heat sealing it with a heat gun, and then using PVA glue (wood glue) watered down to a paint like consistency and painting it on 3-4 layers, you know a layer is done when it is transparent. Make sure to use a brush that you are not attached too since this will most likely ruin it for painting other things. I usually rinse mine in water between layers, but after a while you feel some glue build up on it.

This hardens the foam and makes sure that i have a nice surface to paint on, it also helps to keep the paint from cracking.
Next up is painting it! : )

So next up was a bit of a painting spree, i managed to finish both my backpack and shoulders.
First up the paints i used here was model paints for pigment and some cheaper hobby paint to make it last over a larger surface.
For some simple weathering i used a cheap wide brush, and perhaps stupidly i used a small brush for painting most of the surface

And after a few hours of painting i think it did turn out pretty well.

While i was painting the armor i also did some dry brushing on my pistol and lo and behold it looks like metal!

Now i only have the gauntlets and stomach plate left to paint, and then i got a lot of rigging to do.
 
Lol thanks!

I did test it with a 1.4L water bottle in it and it held up pretty well, i definitly need another magnet and possibly some kind of safety to hold it on if the magnets fail.
as someone who does a cosplay for a character with a backpack and a big one for that matter i would highly suggest adding some sort of strap with a buckle (if you want it to be removable while wearing it) at cons there is such a high probability of something running into you or bumping it on something that without a ton of magnets holding it on its very likely to fall.

This backpack is bolted onto my backplate, but I have a strap that runs from my backplate to my belt in the front, which also acts as a sort of harness and leaves less stress on the back after a long con day

You did fantastic building the backpack, though, which makes me consider building one for myself at some point

At the moment the backpack sits on my back is with two straps and 3 magnets, it is a bit unstable so i am definitely going to remake it later.

And as you say it would definitely be more secure with a proper harness, since the weight does push the chestplate down and up against my neck.
And just as you say sometimes it falls off the magnets when moving a lot, but the straps keeps it from falling to the floor but not from wobbling around. so it works good enough but i do want to improve it in the future.

So im probably going to implement something similar to what you have when i remake my chest in a month or so, right now im in a bit of a con crunch so time is a bit limited. : )

Thank you! im very happy with how it came out.
