LumenPnP

Opulo, the company behind LumenPnP, published a FreeCAD file of the LumenPnP 16mm manual strip feeder on Github. However, the file is hard to use as the part is not visible in the default setting. TechOverflow provides a modified FreeCAD file with the only change being that the part is visible, and a STL file directly exported from FreeCAD.
