Current Filament Sign - Updated-FreeCAD

My printer enclosure has an enclosed filament area on top that can hold up to 8 filament spools.  Since I don't always remember which filament I have in there and where they are, and it is not easy to see the spools as they are arranged in a circle (see the drawings), I decided to make a sign that holds filament swatches for the 8 spools and indicates where they are loaded.  The swatches are square so that they can be loaded in any of the slots and still be readable.  The edges of the swatches are tapered so they stay in the frame.  Since I use several different brands of filaments, so on the back of the swatch I apply printed label tape with the brand name and color if it is special.  The raised filament-type lettering aids in removing the swatches.  I have swatches for PLA, PETG, PCB (polycarbonate blend), and a blank that can have lettering added.  

I recommend that you print a swatch and a frame_unit (just one frame section) to test fit so that you can adjust as needed.  Try the swatch in both orientations as any variance in X/Y size can cause it to jam or at least be hard to insert in one orientation, but not another.

I printed the frame with PLA using a 0.4 nozzle and 0.2 layer height on my Prusa MK3S.  The swatches were printed with the same settings.  I have not yet decided where I'm going to mount the frame.  Although I am now using FreeCAD for my designs, I did basic design of this in SketchUp Pro (which I used to use exclusively) because it is much easier to design from scratch.  I then finalize the design parametrically in FreeCAD to be able to make adjustments easily.  The FreeCAD files are also included.
