Many great business card holders on thingiverse however nothing to match exactly what I needed. I remixed a design by nevitdelmen to add mounting holes for cabinet screws (#8 x 1") and making it a bit easier to print. I provided the Fusion 360 file if you want to customize the design further.
I also included the .gcode generated with S3D to run this print on the Monoprice Select Mini V1.
Hatchbox Wood PLA

This was printed with two(2) layer heights. The first 7mm of the print uses 0.2187mm layer height and the remainder of the print uses a 0.0875mm layer height.
