I bought 1/4 KS tools set, but I did't like the box came with it. So I made smaller case that fits more bits.

Hardware 4x 30-35mm M3 bolt.

Lockable latch Need 1x 20mm M3

34pcs  2x6mm magnets

Also Knipex Cobra fits top of ratchet if ratchet holder is snapped of from top part.

I added 6x2mm place for magnets under every slot, so bits and socket are easy to take but holds well in case.

KS Tools torsion power
