The drill PABH 20-Li B2 from Lidl is a handy tool for making occasional holes into your walls, and comes with a nice set of SDS drills, but these were just put all together in a plastic bag. After I threw away the big unpractical plastic box and was keeping the bits in the bag for some time, it got worn, and bits started falling out. So I have designed an organizer that attaches directly to the drill, and can be easily removed when neccessary.
There are different bit types included - SDS concrete drill bits, screwdriver bits and wood drill bits with hex ends, and SDS/hex adapter. These have slightly different sizes, even those of the same type, and the design reflect this. If your bits do not match the holes, check the photo to see if not try another hole. If a hole is too tight, heating with a lighter / torch and inserting the bit into the warm plastic might help. And if you still need to adjust the hole diameters, feel free to adapt the OpenSCAD source attached.
