What it does

Holds 20 hex bits in two neat rows so they fit in your tool bag without wasting space.
Round holes let you insert bits any way you want, so your markings line up for quick finding.
Printed in flexible TPU material so bits stay put and never fall out or get stuck.
Designed in the USA and made on demand just for you from open-source files.

Your hex bits are finally organized. No more digging through a loose pile or fighting with a cheap plastic holder that breaks. This keeper holds all your bits snug and ready, right in your tool bag.

The design uses two overlapping rows to pack bits tight without bulk. Round holes mean zero alignment hassle; drop any bit in any angle. Your markings face the way you need them, so finding the right size takes one glance. Printed in flexible TPU material from the USA, the fit stays perfect and bits never fall out or jam.

You get the FreeCAD file too, so you can tweak it to match your exact bit set or tool bag layout. Print it yourself or order it printed on demand.
