UPDATES:3/24/2010 IT WORKS!!!!!! Check out my new youtube video http://www.youtube.com/watch?v=7E8CZd66lLI3-9-2010: Check out the Tilt-N-Trap in action!3-4-2010: Thanks to erickphd and his students at Penn. College of Technology we have some modifications to this model. If you have already printed this model, do not attach the Counterweight rail to the Base And tape 2 Quarter to the right side of the Tilt-N-Trap. ErickPHD Said "Testing shows a reasonably reliable trigger at 27 grams but the average mouse is 10-25g so my class thought that it needed to be a bit more sensitive"ADD two quarters and removing the Counter weight rail should give a More sensitive Design.
