Bit holder for the parametric box by and9699. Flippable, easy remove/insert bits (or whole row of them). Fits up to 40 bits.
You need to get the box Fusion 360 file and configure it to internal dimensions 85x62x26 mm. See more details below. Use a bit of filament for the hinge.
Print the insert and five holders. No particular instructions. Personally I have printed everything in PETG.
My own box is not full, I used the bottow row as space for bit tool. With the bottow row turned up-side down it makes a perfect slot for accessories.

Get the box from below link and configure as picture.
(my photos show a special version with window, but that is overkill)
