Tower Bridge Mousetrap

Tower Bridge Mousetrap by Starno Mar 1, 2010

Featured Thing!

Description

A printable mousetrap created for the "Mouse Get" challenge that Cathal Garvey posted on the Thingiverse blog. As I started sketching out ideas, the resemblance to London's Tower Bridge was uncanny, so I decided to go all out with it.

The elevator slides along rails provided by the entrance ramps, however there is only one way to get in. Fievel gets to eat his last meal, but he'll find himself on the ground floor for the rest of the night.

Its un-tested and will need straight rails to function well, so use a fine tuned bot for best results. The design process was a lot of fun, thanks for posting the challenge!


------UPDATE-------

I added Rails_System.zip to the files. This is a dxf and openSCAD file of the sliding rails that was written for easy manipulation even if you have no programming experience or knowledge. I want to optimize the geometry for future applications. Feel free to mess around with it.

Good point. I'm adding this.

Well, there is nothing on this model that hasn't been proven possible to print on a makerbot in the past. However, I may be pushing the limits a little too far by including a few of these challenges all on the same part!

Sure, the rail geometry is not tested and is the first thing I'm planning on printing variations of to optimize for a makerbot. Only thing is I'm out of town till next week, and wont have my personal bot in service till the end of the month.

I will add files shortly that are easily tweak-able so that anybody will be able to test different shapes and tolerances, and we can achieve a well working 'rails' system to use on any future applications. Stay Tuned!

Instructions

-Print out 2 entrance.STLs and 1 elevator.STL
-Add a good amount of peanut butter or cheese against the back wall of the elevator.
-Apply a piece of scotch tape lightly against each slider so that the elevator has enough support to stay up, but is ready to fall with little force.
-Wait and see who visits

Can you print this with a makerbot?

Also - can you post the files to the thing that you made this with? I want to use the 'rails' system in another project

But how does it stay up?

It's Tower Bridge, not London Bridge...

Touch
é. Sadly, it's not the first time someone has corrected me on that either.

Awesome! If it doesn't catch the mouse, it'll look good on my desk! :D
Thanks man, can't wait for my plastic so I can try it!

This is SOOOO Awesome....! I can't believe you even included little steps for the mouse.

Biggest problem will be getting the linear bearings to move smoothly so the bridge don't simply function as a bridge with a snack. :-D

Perhaps you should leave a tiny opening for the mouse's tail too. Since the objective is not to harm the mouse while catching it.
