This is a remix from:

For me it was difficult to take the long bits out of the holder. Therefore, I added a slanted surface on both sides and exchanged the round 10x2 magnets with rectangular.

10x7x4
5 pieces are needed.

Now you can press one on either side and the bits will line up.
I opened the small side for the two bits at the front to make it easier to remove.

I printed it with a 0.6mm nozzle but 0.4mm will work as well...
