For those that have or may be looking for the small plastic fuse box, that is a nice little accessory in the tool roll. These come up from time to time on ebay from kcigermany for a buy it now price of ~US$20 plus shipping. I did a search the other day using just mercedes fuse and found a MB part from samstag sales for a but it now of US$5 plus shipping. There is another one out there (4504937371), but I suspect you can go over to the samstag site (they also sell tools) and find them.
Note: these include a set of fuses, but not the stubby ones.
