This model is not currently offered as a verified ready to buy print.
What it does
- Holds M3 through M8 nuts and washers so you stay organized while working
- Fits standard spanner sizes from 5.5 mm to 13 mm, keeping your parts sorted by size
- Works with greasing if washers feel loose, so your setup stays stable during projects
- Printed on demand to your specs, reducing waste and storage clutter
Your workshop stays tidy when small parts have a home. This holder keeps nuts and washers sorted and within reach so you can focus on your build instead of hunting for the right size.
The design covers the fasteners you use most: M3, M4, M5, M6, and M8. Each slot matches its spanner size, from 5.5 mm up to 13 mm. If a washer sits loose, a dab of grease locks it in place. You get a tool that works the way your hands do, printed fresh to order.

What it is made of
Designs like this print well in PLA. Compare the materials.
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 We have not load tested this design, so we do not publish a weight rating.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.
