Big Box courtesy light cover

This is a light window for the aftermarket Big Box for Vespa scooters.

The box doesn't have a hole for the courtesy lamp as standard and the instructions are to cut a rectangular one and use the original.

This one uses a 51mm hole saw (standard plumbing size) and is made as two sections that screw together for strength and neatness.

Print it in any clear filament but remember the infill will be a feature.

Step is included in case you want to add a logo etc
