There are a lot of things this world needs at the moment.  One of them is a better mouse trap.  Mice are getting smarter every day and if we're not careful we'll end up with Planet of the Mice.  Luckily, with the help of a Makerbot Replicator 2 (its enormous 410 cubic inch build volume and 100 micron resolution, "100 microns!") we can tackle this problem.  And maybe even have a little fun doing it.

The concept is simple:

1 - We set up a real spooky-looking castle.  If movies have taught us anything, it's that a spooky house is simply irresistible to people.  The louder you scream "DON'T GO IN!" at your TV, the more they want to go in.  I don't understand it, that's just the way it is.  Mice should be no different.   We turn the house into a castle for good measure.

2 - Out with the old, in with the new.  A loaded spring just doesn't cut it anymore, we're in the 21st century.  We need to throw everything we've got at this mouse.  That's why this castle is loaded with an Arduino Uno.  Yes that's right, we're talking a jaw dropping 20MHz of raw computational power, 32K of program space and so much more.  The mouse doesn't stand a chance.

3 - Hook up crazy sensors and motors into this digital brain to track the mouse's every movement. (ok, so it's a couple photocells and such, but it should work).

4 - When the mouse ventures into the den of evil we slam the gate shut, hoist the trembling mouse to the heavens while calling upon the gods to bring out the moon and some lightning.  At this point the mouse will be so traumatized (in a good way) that it will bother you no further.  No need to kill it, just send it on its way with a nod of the head and a tip of the hat.

That's the plan.

The truth is, creating this design would not be possible without an affordable 3D printer (aka Replicator 2).  3D printing lets you efficiently explore the inefficient.  The 3D printing revolution is not about printing what you normally buy, it's about being able to create what doesn't exist.  As playful as this mouse trap is, I'd like to think it's along that vein.

I don't have a 3D printer, although I've been drooling over one for a long time.  This Instructable is created to enter the 3D Design Contest at Instructables with the hopes of winning a Replicator 2.  This is what I'd like to make if I had one.  Voting for it would be much appreciated.

With that said, I've done my best to think through this entire project.  I've modeled all components to scale and have confined them to a Replicator 2's build volume.  I've tested out the circuits and micro controller code to the best of my ability.  I've sourced all electronic components from Sparkfun.com.  This is a custom built rig (pulled from the depths of my brain) designed to fit together with exacting tolerances.  If you're looking for a bit of adventure, I think this Instructable is for you.

Step 1: Castle Rundown

Some may call this overkill, but overkill is underrated. This is the most brilliant contraption I've ever seen! Definitely deserves every award out there, mice beware!!
Congrats! This concept is full of win!
Congrats on winning and nice sketching !!
Well Done. Great idea.
Thanks a bunch! Never won anything in my life, so this is pretty cool.
That concept drawing is amazing! GL in the contest, I would really like to see this made.
Good luck as well, your marble pump is deceptively cool!
This is just a fantastic design! I've shared in on the 123D facebook page - I love it. :D
Thanks! I ended up spending A LOT more time on it than I originally anticipated, but I think the end result is pretty neat.
