This is a simple Pokemon Inspired Cubone Skull nightlight.

Assemble with Nightlight insert from here: https://amzn.to/2GhQHYL
(Don't use the dollar store nightlight as it doesn't fit and is dimmer.)
Printed with natural-translucent filament: https://amzn.to/2XpdlnK

To assemble you may need to very briefly use a heat gun.

This nightlight cover is on the brighter side if you use the natural/clear filament so I experimented with painting the exterior white, with mixed results. If you paint it I recommend printing at your finest settings and trying to keep the paint coat light and as even as possible. Also, any more than 1 or 2 paint coats excessively dims the light.

Print Settings: (~3 hr print with 0.4mm nozzle)
*supports enabled
*0.1 layer thickness (especially if you paint it)
*10% GYROID Infill (this infill diffuses the light evenly for the best effect)
*2 side perimeters, 5 top/bottom layers
