This is a nice card organiser for Credit, Membership or Business Cards - and everything smaller. It's a modified version of another Credit Card Organiser I designed: Credit Card Organiser von Kilberisch | Kostenloses STL-Modell herunterladen | Printables.com
This Version features magnets for mounting and a loose fitting for cards. It is using Magnets with a thickness of 3mm and a diameter of 6mm, however if you prefer other magnet sizes, feel free to leaf a comment, I try to add a designe fitting you.
In case you slice the model yourself, I recommend orienting the long edge of the model in parallel to the axis your printing bed is moving.
Warning! Magnets and Cards with magnetic stripes are no good match, so I don't recommend using this holder with a Cards that primarily use a magnetic stripe.
The author remixed this model.
