Bracket to attach a Gridfinity base to an A1 Mini. Requires 16 6x3mm magnets (they about $10/100 on Amazon) and some 3M 10mm wide by 1mm thick double sided tape. The magnets are press fit and are best added while the print is still warm as they will be quite hard to insert once it cools. Be sure to get them the right way round!

Alternatively, instead of magnets, 2.9mm holes are included that will accept an M3 screw (M3x3 or M3x4)

Caution the height clearance is very tight, you can put a 3u Gridfinity object on the A1 provided you use the remixed low profile base that is included. Any higher will be hit by the nozzle.

Once you have the base you can add #M tape to the brackets, use the magnets to to attach the brackets to the base. and then add them to the A1 Mini using the magnetized base to align them.
