Lantern Cover Adapter for Round Solar Lights

We needed to replace the solar light on this lantern, so I made a top that would fit a replacement round solar lamp

The Inside size of lid is just under 4.25" or 107 mm

For lanterns with Handles the holes on each side are 3/16" or 5mm

2 common sizes are 2.9" and 2.4", to get a snug fit I sized them as follows:

2.9" light - 74 mm with 0.5 chamfer
2.4" light - 61 mm with 0.5 chamfer

Tested using PETG, fits well and handles the heat and sun nicely
