Remixed model to utilise 6mm x 3mm magnets x8 to hold lid firmly.

Edited in Bambu Studio, can change negative part parameters to change depth of magnet (currently set at 3mm as the ones I have measure under 3mm).

If changing magnet depth, dont forget to adjust Z height to sit flush with cylinder surface.

Printed in shown orientation with support to give clean exterior appearance.

Added 2nd plate for slightly thicker (2.98mm) magnets.
