This design isn't perfect by any means, but it does snap on easily and improve the look of the storage case.
Due to the overhangs on the Optimized Bambu Lab Accessories Storage Case it leaves the surface of the handles a tad rough. These handle covers are meant to snap on and cover those.
Print different color variants and mix/match your handles!
These fit THIS CASE here by Mr. Sullivan.
