What it does
- Replaces lost pegs so your adjustable shelves stay level and stable

- Print a fresh set in one hour, meaning you always have spares on hand
- Sized small and light, so you can batch print multiple pins at once
You lost the shelf pins again. Your bookcase sits lopsided, and you can't find replacements anywhere. These 3D printed support pins solve that problem. They work as drop-in replacements for standard adjustable shelving pegs, giving your furniture stable support again.
The pins measure 0.19 inches in diameter, sized to fit snugly in 0.185 inch holes. This dimension comes from real testing with 3D printers and actual shelves, so you get a fit that works. Just insert them into your bookcase or cabinet holes, and your shelves hold level and steady.
Print a handful in about an hour. Keep extras in a drawer. When a pin goes missing, you have a replacement ready to go.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
