Simple City side light design. Feet should just push into base, but you may need to resize hole/plugs depending on your printer.

Printed base and top at 0.20 layer height, feet at 0.35, all in PLA on i3 MK2. I used normal opaque white PLA for the top part. It is very thin which acts as a good diffuser.

You will need to add bulb holder and plug / cable etc (I used ones from 2 cheap IKEA side lights which were £3 each)
