Disclaimer: this toy isn't a toy. Some of the spikes are sharp. Be careful assembling it.
Spring Razor from Dishonored. I eye balled this from clips out of the game. Several different revisions, and I think it looks pretty authentic to the game. IMO it's MUCH more accurate then the one Bethesda had on display in the E3 booth. The spike feet, and upper arms are attached with brass screws, so they could move if this was a real weapon.
I wanted it to be more then just a chunk of plastic, so I wired the ring pin to the shrapnel. It's a bit gimmicky, but the shrapnel will move a bit when you pull on the ring pin, giving the illusion that this actually does something. Don't play with it too much, or you will snap the wire. (Major PITA to fix) Think of it as a Spring Razor bobblehead.
Other then the parts you print, you will need the following to assemble it like mine:
Hardware was all from local homedepot. If you can find the right length screws you don't need to cut them.
(6) #6 1" brass screws (I cut them down to size)
(1) #6 steel nut (used to fix the threads if you cut the screws down)
(6) #6 brass nuts
(12) brass washers (that fit the above screws)
Scrap Cat5 (network) cable. (Disclaimer: don't play with fire) I carefully took a lighter to the wire, and stripped off the plastic coating.
Print everything. You need 3 upper arms and 3 feet.
Remove the support from all the parts. I had to use a small drill bit and then break the support out for the ring pin hole through the base.
You WILL break spikes while trying to remove the supports on the shrapnel ring. I made several prints of this making adjustments to fit around parts, and managed to break off spikes every time. Use fine tip screw drivers and pliers to remove the supports. Glue any spikes you break with superglue and sprinkle some baking soda on the glue to set it fast. It doesn't really need to look pretty, since it's supposed to be a pile of jagged metal.
Glue the cone wire guide into the center of the base above the hole. Glue the bottom strap mount to the bottom of the base. It's easier to paint this if it's attached to the base. Orient the hooks for the barbed wire between the upper and lower arm mounts.
Clean, dry, and paint everything. I gave all the parts a coat of matte krylon fusion paint as a primer, and then brushed acrylic for all the visible colour.
Take a length of 1 strand of cat5 network cable (or whatever wire you use) and wrap it around the ring pin a couple times. I used the brown wire. Use an extra long piece. 1 foot should be lots. All the extra will be cut off, when all the parts are attached, and the shrapnel ring is tensioned. Put a dab of superglue on the wire wrapped area to permanently bond it to the ring. Feed the wire through the hole to the center of the base. It will take a while, but eventually it will work it's way out the center.
I assembled everything with the wire in place, since it would be very difficult to feed it through the entire assembly.
Feed the wire through the conical spring. Put some superglue on the bottom of the conical spring, and carefully center it over the cone wire guide. Let the glue dry.
Loosely install all the arms with screws/nuts.
You will have to drill a small hole for the wire in the top of the shrapnel ring. The tighter to your wire size the better. There is a piece of support in there I couldn't remove.
The upper arms will determine placement of the shrapnel ring. In the game the ring pin (grenade pin) is facing away from you, and too the left. The shrapnel ring fits around the upper arms, but to be accurate to the game, the lever arm (that the wire goes through) should go side to side. You will notice the smaller of the spear shaped spikes will face away from you. One of the upper arms, will semi lock into the lever arm.
Here is the hard part. This is where the extra wire comes in handy. The shrapnel ring is tensioned with conical spring against the ring pin. Feed the wire though the shrapnel ring, and then apply a small amount of superglue to the top of the conical spring. Try to not get it on the wire or the hole the wire goes through. Carefully lower the shrapnel ring onto the conical spring while you pull the wire through. You have to get the orientation/placement correct before the superglue sets, so test fit it first. Hold the shrapnel ring in place while the glue sets, and jiggle the wire to make sure it doesn't bond to the part. You want the wire to move freely, you are just bonding the shrapnel to the spring now.
You now have a spring razor bobblehead.
Pull the wire tight so the ring pin is tight against the side of the base. The shrapnel ring should sit just below the surface of the base. While you pull the wire tight and hold the shrapnel put a dab of superglue in the hole the wire goes through. Hold it till it sets, or drop some baking soda on the glue to speed up drying. Cut off the extra wire, and put a dab of paint over the superglue.
When you pull on the ring pin, the shrapnel should move down a tiny bit. Once again, don't go crazy yanking on it. After I finished assembling mine, I managed to snap the wire, and removed some extra springs from an earlier revision. It's a bobblehead, that pulls the ring pin tight.
Disclaimer: don't play with fire.
I used a lighter to remove the plastic coating from network wire to get bare copper for the barbed wire running over the shrapnel. Lightly run the wire through the flame, pull it out of the flame, wait a few seconds and pull on the plastic with pliers, or your fingers (IT WILL BE HOT)
I wrapped a couple small pieces around the wire to create barbs, and then twisted it to hold the barbs in place. If you put a loop on the ends, you can pull them tight against the hooks on the bottom of the part. Orient the wire how you like. I just looked at some pictures from in the game. If you loop a piece of the wire, around a screw driver, and then put the loose ends in a drill, it will give you a nice tight twisted wire.
Attach a couple thin leather straps to the bottom part through the square holes, and hang it on your shoulder strap next to your bone charms.
