Introduction: 3D Printable Rubber Band Gun (With Prank Mode!)

*This is a Contest Entry: Please Vote if you think this design is worthy to win a 3D Printer (Makerbot Replicator 2), I will be Truly Grateful, Thanks*

This is my 3rd entry after the 'TriStand QR 3D Printed iPhone Case' (an iPhone case with Build In Stands and a personalised QR Coded Business Card!)  and the 'Rubber Blaster iPhone 5 Case' (Rubber Band Gun in an iPhone 5 Case!)

What is it?
This is a home 3D printer friendly rubber band gun with a secret prank mode!
In the normal mode, this gun can be used to shoot elastic bands at a target or even better, a workmate.
When a secret switch is switched however, this gun enters Prank Mode!
Once in Prank Mode, hand to a friend or workmate, as they pull the trigger aiming for you, the prank mode mechanism inside means they end up shooting themselves!
This Rubber Band Gun has been deigned with 3D Printing in mind and the attached files (attached as a .zip) can be 3D Printed using most home 3D Printers in 1 print by printing the 8 pieces which are then easily assembled together (watch the video to see how to do this)

As I don't own a home 3D Printer (hence the competition entry) I have not tested how well this works. If anyone prints it, please post pictures in the comments as I will be very interested with the results.

My Background
I got into 3d printing the second I first read about it and have been hooked since. It's amazing how anything you can think up can then be turned into a physical object and how anyone can be a designer as I have demonstrated here. I teach myself how to use CAD (Computer Aided Design) program's by constantly improving techniques through trial and error. Everything I design, I design with the hope of 3d printing it.

I am currently using Shapeways (a 3d printing bureau service that after uploading your design, mail you the prints within 2-3 weeks) based in the Netherlands for these prototypes and am currently using the little profit from selling other designs on the site to create and print prototypes of new versions and designs. It takes weeks at a time for them to arrive and costs a lot more than home fabrication units (3d printers) can print due to the low cost of ABS / PLA filament, it would be so useful for me to expand my designs and hold them in my hand within hours, not weeks; also let's face it, who wouldn't want a 3D Printer, It would also be incredibally awesome to own one of these incredible machines however I don't have the spare cash (so please vote for this design to win, thanks). Check out My Shapeways Shop which contains more items I have designed (such as my latest idea which has yet to be printed: "Rubber Blaster iPhone 5 Case" a rubber band gun in an iPhone case! I have also modelled a rubber band gun with a prank mode (the shooter ends up shooting himself if a hidden switch is switched!)) Lastly, showing my passion for 3D Printing, I am a former Winner of the Gizmodo UK 3D Printing Challenge after designing a moving gymnast performing a backflip! (There is a video on the page)
In conclusion, I am sure that this MakerBot Replicator 2 won't be wasted on me and will be used a lot!
