Gridfinity Compatible- Universal Hole Grid Holder – Tool Organizer 5-25mm

I needed a simple holder for organizing many drill bits of the same size, but couldn’t find one that fit my needs, so I designed this universal grid holder.

The block measures 41 × 81 mm and features a grid of identical holes. It’s available in multiple hole diameters ranging from 5–16 mm, plus 20 mm and 25 mm versions. This makes it ideal not only for drill bits, but also for Dremel/rotary tool bits, pens, markers, and other similarly sized tools.

For best fit and easy insertion/removal, I recommend choosing a holder with holes 1 mm larger than your tool diameter. For example:
6 mm drill bit → use 7 mm holder
13 mm pen → use 14 mm holder
