Remix of https://www.prusaprinters.org/prints/9077-parametric-bit-driver-hex-2mm-to-10mm

I have made the original design to be doublesided. You can choose the 4mm or 6.25mm version. Both are in reality a little bit bigger so the bit can be inserted easily but you can change the size of bit in .scad files as you wish.

Enjoy!

Print instructions

You can insert magnets to the bit hole. Put pause in your slicer to layer 65 and 600.

Be aware not to break the print from bed when pushing the magnet in as it happened to me twice. I have printed it on textured sheet with glue.

I have printed it in PLA, 15% gyroid infill with 3 perimeters and big brim and it is reasonably rigid.
