Glyph Discs (Deeper Engraving)

I tried printing the original Glyph Discs by MrMeepson, but was unsatisfied with the results (I used HATCHBOX blue glow-in-the-dark filament (1.75mm) on my X-Plus, but the resulting discs were nearly see-through and the design was invisible). I decided to improve on the design by making the glyph design more defined and increasing the infill settings on my printer from 20% to 95%, which yielded far better results.
