This is a design for a display shelf inspired by and based on the Mini Floor Stands by muzz64. It utilizes the same print-in-place folding arm, but the hinge is designed in three parts to allow for the sign to fold flat. This is specifically designed to hold 16 of the Mini Floor Stands, printed at either 50% or 70% scale. I could not design one for 100% scale signs because the required print volume would be bigger than any consumer 3D printer, kit or otherwise.
There are two versions, and STLs for both 300 by 300 mm and 400 by 400 mm print beds. The sign will stand about 350mm tall on the 70% scale version and 300 mm tall on the 50% scale version. Dual color printing is an option, but depending on the STL it may be very difficult without a dual extruder.
Some prints won't need supports, i.e. the ones laying flat.
It is not possible to print either version flat on a 300 by 300 mm print bed, making color changes very difficult without dual extruders. The 70% scale version has a file for printing with color changes if you have a 400 by 400 mm print bed.
Two of the STLs seem to have a small bit of something floating in midair above the print, this does not show up in TinkerCAD so I'm not sure what it is. If it shows up in your slicer, you should be able to remove it fairly easily.
- Remove any supports.
- Assemble the hinge.
-The hinge pins may need sanding to fit properly, depending on your printer's precision.
- Unstick the middle arm, and slot it in place.
