When you have a hammer, all of your problems look like nails. When your problem is a nail, you're kind of screwed if you don't have a hammer. Unless you have five cents and a 3D printer! This simple model lets you quickly print a five-cent "hammer" that is small enough to fit in your pocket. Pause the printer to insert your coins when appropriate. The demo models are for holding five US pennies; if you want to use some other kind of currency, then make your own cheap hammer by clicking the "Open in Customizer" button. WARNING #1: When you add the coins, make absolutely sure that the top coin does not extend above the current printed material; if your printer catches on the coin then either your model or your printer could be damaged. WARNING #2: Although this "hammer" is safer than using a drinking glass, you could actually hurt your fingers if they slipped off the tool and onto the nail you are driving into the wall. Please use caution and always use a Real Hammer if you have serious work to do. ===== Twitter: twitter.com/mathgrrl Hacktastic blog: www.mathgrrl.com/hacktastic Shapeways geekhaus store: www.shapeways.com/shops/mathgr...
