Basic support for using a rectangular hygrometer on the printer frame, in front of the door. The two 8x3mm magnets are inserted under pressure from the inside, before inserting the hygrometer. You don't need glue or anything like that, the magnet itself will do its job inside since there is only a wall between the metal structure and the magnets.

Note: Added stl with 10mm, 6mm and 4mm magnets

If you need versions with magnets of other sizes, please comment.

Plate 1: 2x 8mm magnets

Plate 2: 2x 10mm magnets

Plate 3: 3x 6mm magnets

Plate 4: 8x 4mm magnets.

The maximum depth of the magnets can be up to 4mm.

I also include version 1 (STL only) without reinforcement and with the insertion of the magnets on the outside (they will need to be glued).
