My fridge's shelves are so badly designed that if you push it all the way to left or right (not centered), it can fall off it's bracket. Fun!

This piece snaps onto the corner rail of a fridge shelf to keep it snug against the fridge wall. It eliminates unwanted movement and keeps the shelf centered in the fridge.

To be printed in TPU. It's designed to grip firmly onto a 6mm rail for a secure fit.

Since I installed these corner blocks more than 2 years ago, the shelves have been a lot more stable and the TPU blocks still hold in place perfectly.
