So i made these 2 bit holders because i wanted bit holders that could hold all the bits in one grit. AND fit into the box i printed which is the parametric box from Pred.

I made them to fit super close so its not easy to pick them with your fingers, but i never do that anyway i have a magnetic bit driver and it picks them out of there just fine, i think that is way easier..  Just keep that in mind before printing!

The 4mm bit holder takes 30 bits.

The 6mm bit holder takes 16 bits.
