I bought this 13 piece titanium metric drill bits from Amazon, https://www.amazon.com/gp/product/B00M4U3Y34/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 but the case that it came with was not that great. The hinge was cracked so it did not stay closed and the labels for each drill bit size is very hard to read. Instead of trying to fix the hinge and have it probably not last I decided to use joaquinfq's "Customizable Drill Holder". This allowed me to create a case that holds the drill bits nicely.

I imported the file that the customizer outputted and I added numbers to identify each drill bit size.

I also create a little grabber that holds a magnet. Some of the drill bits are small which makes them hard to get out. The grabber holds a square neodymium magnet sized 5mm x 5mmx 3mm. I bought mine from Wish (https://www.wish.com/c/54acfc554274a22214c95a6e).

I then took a metallic silver sharpie and colored the top of each number to make them stand out a bit more.

The cover at first was tight but is a bit loose now so I just use a rubber band to keep it all secure. I don't know if I would trust the lid even if it was tight.

edit: I have included a wood drill bit holder for pimar3D. He wanted some changes for the box to hold 3mm x 62mm, 4mm x 75mm, 5mm x 86mm, 6mm x 92mm, 7mm x 110mm, 8mm x 117mm, 10mm x 134mm, 12mm x 152mm, 14mm x 170mm.
