These holders securely store CNC tools, drill bits, and other things with 1/8", 1/4", and 3mm shanks.
The 1/8" and 1/4" Bulk versions hold up to 77 and 21 bits, respectively. These point the bits straight up, so you can't stack on top! Be careful not to hurt yourself!
The Tube version holds 12 bits in their protective packages. You can stack other blocks on top of this.
The Jewel Insert version holds four detachable sleeves from snap-together jewel case packaging. These usually hold 10 bits. You can stack other blocks on top of this.
Gridfinity Tips!
- No brims or support required!
- Use any filament with an 0.6mm or smaller nozzle.
- Wider bins can curl, so maximize your bed adhesion if you're going big!
- All storage blocks are compatible with all baseplates!
- Most storage blocks are stackable!
- You can add 6x2mm magnets to the corners! They won't magnetize the contents.
- You can also use M3 screws in the corners.
Gridfinity was inspired by Alexandre Chappel's ModuBOX system, which is found at https://www.alch.shop/shop/assortment
















Thanks for posting! Any chance of a parametric version? I have 4mm bits and 6mm bits. I was also thinking it would be cool to extend the sides of the bit holders to make them stackable.
How do we get access to the fusion files? The links give me:

Thank you for posting the parametric Fusion files. The original Tubes model has 13 mm grooves to hold 2 rows of 6 bits in 12 mm square cases. I used the Tubes files to model a bin with 8 mm grooves to hold 1 row of 10 bits in 6 mm diameter tubes.
