Trolley Key

Just a simple gadget for the busy shopper. A trolley token with an easy grip to remove it when finished.
It can be fitted to a keyring so it is always handy.
I have included the plain 123d file so that anyone can customise their print - not everyone will appreciate the word moose on their trolley key!

How I Designed This
One circle
One isosceles triangle
One half circle
A trip to the british mint website to get the size of a one pound coin
then i extruded the drawn shapes to the right thickness (3.15 mm) centred them length ways the moved them till they overlapped and looked ok and combined them.
I then made a 3mm rad octagon and centered that close to the grip end for the keyring hole then added raised text.
et voila...
