This instructable was strongly inspired by "Build the Starship Enterprise from useless office supplies," so thank you instructables user bchafy! And if you make it, send me pictures!
Step 1: You will need:
1 chisel sharpie
4 pen lids
1 small pencil sharpener
4 2" brass fasteners
2 medium binder clips
2 large binder clips
1 defunct memory chip or similar
1 strip of staples (not pictured)
epoxy or hot glue (hot glue works a LOT better)
Step 2: Wing base
Glue the memory chip under the clip of the sharpie. You don't actually need to use glue as the binder clips will hold it in place, but I highly recommend it for structural stability.
Step 3: Wings
Remove the legs of the binder clips. Replace the legs of the medium clips with the legs of the large clips. This takes a bit of force but it can be done!
Step 4: Wing assembly
Clip the medium binder clips to the memory card. Use some glue here too if you like to prevent future wobbling. Glue the pencil sharpener in place for the cockpit.
Step 5: Thrusters
Beginning with the underside, glue the pen lids in place for thrusters (I suppose you could use tape, but glue looks a lot nicer). Glue two of the fasteners on the bottom wings for cannons. Tape will hold them in place while the glue dries.
Step 6: Finishing steps
Glue the top two thrusters on. This is the fiddliest bit as they don't have anything to rest against. A little blob of poster putty will be your good friend here. Glue on the top two cannons, and glue a strip of staples behind the cockpit to give more body. You are done - unless you can think of some way to add an R2 unit. You can also use one of the discarded large binder bodies as a display stand.
Okay, I really need to get back to work now.
