Shopping cart opener - works in many countries

This small gadget will let you open most shopping carts for euro coins. To use in other countries, please scale (in all axis) to different size.

I noticed there are many gadgets of this type, but I designed this one from scratch and performed testing with variations.

I tried many shapes and this one seems to work best.

Just insert straight into the hole and remove with slight wiggle (side to side and pull).

Includes a hole for the keyring.

Great if you have leftover of approx 60cm of filament.
