The non-XL version of the Optimized Bed Scraper is exactly 42mm wide, which happens to be the exact same width as a 1x1 gridfinity bin. The bin holds one scraper and about 14-15 spare blades.
I like adding debossed icons to my gridfinity bins, so I added a silhouette of the bed scraper blades to the bin. If this is not for you, there's also a bin without the icon.

The bin was generated using the FusionGridfinityGenerator addon.
The author remixed this model.
Basically rebuild this bin from the ground up. Halved the bin width and made it compatible with the non-XL version of the Optimized Bed Scraper. Also made the bin a bit higher so that it is 5 units high (the original seemed to be 4.5 units high).
The only thing I kept unchanged is the width of the blade compartment and the chamfers.
