Loki's Chitauri Scepter from The Avengers (2012)
This a replica of the short staff Loki used to mind control Hawkeye and several others, and escape from the SHIELD compound. This item is approximately 96 cm long (36 in).
Notice: This device will not grant you the ability to fire energy blasts or take over the minds of your enemies. Such upgrades are welcome as derivatives.
Assemble (not the heroes)
Take over the world
I printed the staff with ABS, 2 shells, 0.2 layer height, and 10% infill. Some pieces do require support. Included is the staff sliced to fit a Makerbot Replicator in .stl files (may not be oriented for minimal support). If you need to slice it differently, I've also included the .skp file with the original designs in it. All names referenced below should match the .stl file names.
Note: Pieces have small holes for short segments of ~1.7mm filament. These are used for test fitting and alignment for gluing.
If you do not own a 3d printer, the design files should allow you to make your own scepter out of wood or other carvable material. Much of the process after cutting out the segments will be the same.

1.5 Meters Wire, ~18ga
9v Battery Harness
Number and type are your choice
I recommend using a mix of 80%/20% white to blue.
these should be selected to allow your LED compliment to work with a 9v battery.
Sub-mini toggle switch
1/4" hole size
The switch slot is about 3/8" x 1/4" x 9/16" include space for wiring.
Appliance Light Bulb
Blue Ant Farm Gel
Clear silicon caulk (Optional)
Plastic friendly paints and primers
Bronze or antique gold for the staff
Steel for the blades
Metallic black for the flats of the blades
Rare Earth Magnets (Optional)
1/16in thick by 1/4in diameter
Amazon: 30 Neodymium Magnets 1/4 x 1/16 inch Disc
Once printing is complete, remove all support and sand pieces smooth.
Freshly printed part. If I was a little smarter, I would have arranged the part to print with less support.
Parts sanded and being test fitted
After pieces are prepared, glue mirrored pieces together except for the haft base and haft-covers. These are the end pieces on the left of the above image.
Attach the wire to the switch, at least enough to reach from the switch compartment to the gem location and still have enough slack to work with. Insert the switch into the half base (see below) and run the wire through the rest of the half.
The switch goes in the little compartment on the right. Excess wire goes in the space to the left.
Glue the haft segments together into one piece, mirrored pieces first. Glue one of the haft-cover pieces to the haft. Leave the other free; this piece will be your battery cover.

Major assembly completed. Filled in gaps between parts. Final smoothing and filling .
When painting, make sure you use a plastic safe and friendly paint. Make sure you pay attention to what materials the paint is for; using the wrong paint means it will never fully dry. Otherwise it will not adhere well or dry fully. Allow stated dry times for each layer.

Making the Gem
The gem is an appliance light bulb. I used a diamond Dremel blade slice off the metal base. The bulb was then coated inside and out with a few layers of clear resin to prevent shattering.
The blue insides were made from the translucent blue ant farm gel. I prepared a batch and let it fully dry. After it was dry, I shredded it into chunks and let those dry. These chunks were then used to fill the bulb.
The last stage is to wire the LEDs up and insert them into the bulb. If you know your electronics basics but are unsure how to figure out the LED and resistor relations for a 9v system, use http://ledcalculator.net/
. If you don't know your electronics basics, get a friend to help. This is a pretty basic circuit but there are a lot of variables as to what one can do here so I leave it to you.
Attach the length of wires to the LED circuits but not to the 9v holder or the switch yet. That is for after final assembly.
Additionally you should seal the wire connections near the bulb to prevent any moisture from shorting out the circuit. I didn't on my first setup and the LEDs were fried by the end of the day. One my second, I used clear silicon caulk to seal all the LEDs and associated wires into a single mass.
Ant gel drying. Ignore the glitter, it was an attempt that failed.
'Gem' with 100% white LEDs. Mixing in blue LEDs to get 20% blue make the colour much better.
Glue the small blade pieces to the main haft.
Run the gem wire through the codpiece and glue the gem to the codpiece.
Glue the neck pieces together and to the haft. See the model for how these pieces are named and arranged.
Neck piece 3 goes into piece 2
Both those go inside piece 1a
Piece 1b goes outside of 1a
These should fit together easily
Piece 1 has pillars which fit into the haft and have keyholes in neck piece 2 and 3.
Run the gem wires down the center of the haft. Using 18ga wire did not result in any problems.
Don't pull too hard on the wires, otherwise you may dislodge your LEDs.
Glue the codpiece to the rest of the assembly. The gem should be resting on the back of the short blade.
Glue the large blade to the scepter. This will slide into neck piece 3.
Glue the jewel holder (remaining two flat and small pieces) to large and small blades. This should sit just above and around the gem.
These pieces may need to be heated and curved depending on your setup.
Make the final wiring connections
Trim the wires to length. Excess wire will make fitting the battery into the compartment difficult.
Connect the positive line from the LEDs a line coming from the switch.
Connect the negative line from the LEDs to the battery holder.
Connect the positive line from the battery holder to the other switch wire.
(OPTIONAL) Glue the magnets into the haft base and the haft base cover. These will be a tight fit.
Make sure the magnets line up for polarity. Otherwise the cover will not want to sit.
Enjoy being burdened with a glorious prop.

ENOUGH! You are, all of you are beneath me!
I am a god, you dull creature, and I will not be bullied by...
Do not allow Deadpool near your scepter. Silliness will occur...
