Business card holder with nameplate (OpenSCAD)

Two pieces version (with replaceable insert):

I went through quite a few iterations to come up with a working model but I am happy with the results.  I wanted to be able to print the text with a color change which meant it needed to be printed face up.  I also wanted to avoid supports.  A separate insert is the solution that I came up with and with the added benefit that it can be printed in a different color accent and easily be replaced if there is a need to change the text.  I added an access hole behind the front wall to help push out the nameplate when replacing it.  I also wanted to avoid glue and screws so I came up with a shape that stays in its place in the receptacle mechanically with just a bit of bending to insert it.

The text can be set in OpenSCAD customizer panel.  I know that OpenSCAD can sound scary but it is easier than you think, give it a try, no code change needed!

If you want a different color for the text on the nameplate insert, you can split the STL to objects in the slicer, print the nameplate insert separately and insert a color change (also in the slicer).  Or… you could just use a metallic Sharpie like I did with the gold and red text samples shown in the pictures.  The purple text version was printed with a color change.  The color change height is shown in the OpenSCAD console to help you set it up in the slicer.

In OpenSCAD, the nameplate insert will be shown at its place in the receptacle when previewing but it will be placed on the plate when rendering and when exporting as STL.

One piece version:

I designed this version to be printed face down to have the texture of the build plate on the front with the text.  The OpenSCAD model will generate the text facing down but you can rotate the model in your slicer if you prefer to print with the text facing the top or the front (depending on your texture preference).  I’ve been pretty agressive with the overhang angle to maximize the card capacity but you can adjust the angle in OpenSCAD if your printer struggles (it printed nicely on my Prusa i3 MK3/S+).

The text can be customized in OpenSCAD or you can simply print the STL with no text if you need a simple card holder.  There is also an STL with a classic « take one » text.

To customize the text in OpenSCAD:

1. Change the text on the first line of code (line 7) or in the customizer. 
2. Click on the render button 
3. Click on the export STL button.
4. Give it a try, it is easier than you think!

I printed my test model with PETG using a 0.4 nozzle / 0.2 layer height / 15% infill on a textured sheet.
