I know - totally overdesigned - but it was fun to create the frame with Fusion and a good exercise for me ;-)
One lesson I learned: always let your printing plate cool down completely - then you'll have it in an undamaged condition for longer ;-) Slightly impatient or under time pressure and the print plate coating is already ruined...
For serial prints, I have constructed a small storage frame to cool the plates completely, which I simply place on the Bambu, because there is usually no more room on the work table and it is only in the way anyway. Five small rubber studs are glued underneath and nothing slips away. There are four additional holes for storing the frame - depending on how you are holding the stand ;-)
