Filament sample spool

prusaprinters

I removed the honeycomb pattern from the model since this feature prints faster and stronger when generated in the slicer.  I also added a perpendicular hole to hold the start of the filament, removing the old hole.  The slicer files also have negative spaces to remove the inner rings of the spool to further reduce print time, as well as height modifiers to add in the honeycomb pattern as infill with no top and bottom layers.
