All the parts have been recreated to be easily printable without particular equipments – it just take a pretty long time to print all the parts.

The main body should be printed in its final position and it requires supports – I printed mine with the "buildplate touching only" option checked and it bridged pretty well the other part. I think that cura tree supports could also work great. Any resolution is ok, mine was 0.24mm

The screws should be printed with the round part facing the plate, without supports. A small layer height is most suitable for the screw to work properly.

The cards are designed to be printed with 5 layers 0.16mm tall, with the first two layers in one color and the other tree in another. To do this a simple filament change M600 code or equivalent is ok.
You need a very good bed adhesion, to avoid warping on the parts – even if a little warp on the corner can easily be fixed with a heat gun or an hair dryer.
