Exploding Piggy Bank

thingiverse

I still haven't printed this.\nTechnically, you can fit a standard spring and latch mouse trap inside the base, then assemble all parts by gluing the face and feet onto the body while leaving the base and body separate to move freely. The coin slot aligns with the trigger of the mouse trap, so when someone drops in a coin, the entire piggy bank should explode apart. \nNote: I'm not sure how much variation there is in mouse trap sizes. I used a Victor mouse trap as a reference model. The rectangular base of the mouse trap measures 3 7/8 x 1 13/16 x 3/16".\nI don't see why it won't work, but I still haven't printed it yet.\nI added 0.5mm supports for the face recess to ensure a smooth print, so print without supports and trim off the excess fins. Glue the face to the body and the feet (print four) to the base. The adhesive used needs to create an extremely strong bond since this device will be subjected to a lot of force.\nI've included the SketchUp model for anyone who wants to experiment with it.\nThe face is an approximate remake of RyGuy's 8-bit piggy bank (http://www.thingiverse.com/thing:16474), I just added a smiling mouth to give it a more cheerful look.
