Rollstop: Never again rolling shopping carts!

Rollstop: Never again rolling shopping carts!

Do you know this too? You load your shopping cart, turn around briefly, and it rolls away – straight into the next car or, in the worst case, uncontrolled down the parking lot. Now that's a thing of the past!

I present to you Rollstop, your new, practical companion for shopping. Rollstop is a cleverly designed, mobile stopper that you simply place in front of the wheel of your shopping cart on the ground. Then you push the wheel into the stopper, and the shopping cart's own weight holds the stopper firmly to the ground. This ensures your cart stays exactly where you left it, even on slight inclines or uneven ground.

The advantages of Rollstop at a glance:

• Secure fixation: Reliably prevents the shopping cart from rolling away using the cart's own weight.
• Easy handling: Simply place it on the ground and push the wheel in – no complicated attachment.
• Compact and mobile: Fits in any bag and is always with you.
• Robust design: Designed for daily use and long-lasting use.
• Perfect for 3D printing: A great way to show off your skills and print a truly useful gadget.

Why Rollstop?

I developed Rollstop because I myself was often frustrated by runaway shopping carts. This small but fine aid makes shopping more relaxing and safer – for you, your car, and everyone else!

For stability and longevity, I recommend printing Rollstop in PETG. This material offers the necessary robustness so that your stopper can withstand the stresses of everyday life.

Should the shopping cart wheels in your shopping center not conform to the standard, no problem! You can easily scale Rollstop in your slicer to adapt it to the specific wheel sizes.
