Initially made for Chacon 54365 product (see link and pictures), this adapter allows you to mount all kind of similar female wall mounting systems to the Big Builder 3D Printer. The Chacon model is displayed as an example. By the way, it is very useful to monitor energy consumption converted in week / month / annual costs. And I don't have any interest in this company, just in monitoring my 3D print costs 😉 Spacing : 34.5 mm Pin head diameter : 6 mm Pin height : 5 mm
