Printed in PETG transparent filament. Works very well. PETG is very very hard (when not molten) so added extra infill in the base as even the slightest tear in the infill would make the print head snag. Lighting is WS2812 leds wrapped around a supporting cylinder. Did not use the magnet lock, instead it can be opened by inserting the top part into the bottom. Made a hole for the "ruby" in the bottom and printed this separately.
