NOTE: I made an updated version of this design that you can find here
A parametric version of the supermarket coin thingies that you can use to get a cart without needing an actual coin.
Bonus: you can pull the thing out again and don't have to leave it in the cart, which makes it harder to loose it.
In the .scad file you also have the option to add a dxf file if you want to have a small logo embossed in it.
The stl file is configured to work for carts that accept 50 eurocents or 1euro.
- Create a .dxf file that is slightly smaller than your coindiameter (optional, if you want to have a logo)
- adjust the parameters to the values you need (the default values are fine for carts that accept 50 eurocents or 1 euro.)
Using the folliwing settings should be fine:
- Have fun!
