This model was born after I've printed the OPENSESAME3000 created by cartisky . I like the idea of the device itself, but wanted something to store it easily in the kitchen.

It's a basic holder that can be mounted to a fridge or something else with double sided tape or 4x 6x2mm (6x3 should work as well) magnets. The magnets have a tight push fit, so they hold without glue.
