Also works with AMS modules.

The upper glass is raised by 20mm and a ventilation slot is created on all sides. For example, with a PLA print, the heat is vented at the top. Glass plate is also held in place on the spacers with a form-fit. Leave the door half open or so for good ventilation. An additional benefit is that the filament tube no longer touches the glass and therefore no abrasion is produced.

No magnets or support material are needed. Only 47g of filament is needed for the four parts.
