Picture of Protect Thyself Moneyclip
Here's the situation:  You and your sweetheart are walking back to your car after a great movie, when out of the darkness, a thug comes up to you and demands all of your money.  You calmly reach into your pocket, remove your moneyclip and offer it to the robber.

A moment later, you're pocketing your money and walking back to your car.  The thug is where you left him, writhing on the ground in agony.

Enter the non-leathal, but none-the-less diabolical Protect Thyself moneyclip.


Be forewarned... This is not a toy, nor should it be considered as such.  If you would rather be a victim and surrender your money with the hopes that the bad guy will say "thank you", shake your hand and leave, then this is not for you.  If you're the type of person who'd rather defend yourself from lowest element of our society, then be sure you have the training to use self-protection devices such as this.

I'm not responsible for your safety, training or ability to make, or handle or use this moneyclip in a dangerous situation.  If you decide to make it, decide carefully... And use it responsibly.

Step 1: What You'll Need:

Picture of What You'll Need:
The first think you'll need is the attached 123D file, a 3D printer and ABS or Nylon plastic.  If you don't have those or can't have it printed by AutoDesk, I've included dimensioned images so you can make one out of any material you'd like.

A sheet of sandpaper, a 1/8" pop rivet and a strip of .020 Stainless steel measuring 2-3/8" x 1/2"

If you're printing this in ABS, you'll also need a mixture of ABS and Acetone to weld the parts together.  If you're printing with Nylon, the best way to attach the parts is mechanically, using sheet metal screws.

Tools you'll need will be pliers, a vise, hammer, popsicle stick (for the cement) and a scraper or knife to clean the weld line up.

lol Poofrabbit... I take it you show magic to your students. I mentor young, at risk kids; and knowing how cruel others can be to those needing additional attention, I decided magic would make all his/her classmates jealous... It backfired on me the first year I tried it, and now, 6 years later, ALL the kids have gotten the word and always plead to go with us... And the teachers are more than willing to let them:)

Thanks for your comment... Closeup, Stage? You go to any conventions?
