This is an improved version of my original Hex Bit Adapter for converting hex bits from 4mm shaft to 6mm standard hex bits. This is a very useful adapter particularly if you use a mini electric screwdriver like the Wowstick. It allows you to use it with regular hex bits.
This version has an internal slot for a 5mm diameter x 2mm tall round magnet. This little magnet is more than capable to hold the bit inside the addapter.
The best part is, if the adapter breaks, just re-print another one and reuse the magnet.
