I did not know where to go with my small 250Gr. spools. Fitting on the normal back-holder of the A1 mini is a solution but due to my snuggly set/up environment not so very handy. So I made a On top Small Spool holder for 2 250 Gr. spools. It all fits together but clicking it in. Maybe a super tiny bit of cleaning necessary. The round holder is placed on the central Bambu logo in the middle of the AMS lite, the cubic holder is placed in the round on, the stick is placed on the cubic and the roller holders are fitted on the stick. See photos. This last piece is glued.

On the Photo you see the base version. this a corrected version with better fitting roller holders. Created by a CAD and printing newbie noob. But it works great. Thank you all for your great designs
