Created an alternative cap that does not need any supports when printed.

remixed the base to add hole place for the lamp cord to go instead of needing to drill it.

Infill was printed at 30%,might want to adjust based on your filament choice.

Infill pattern will need to be archimedian chords to avoid any odd-varible density of light pass through. Do not use concentric infill as it will leave floating infill walls that will ruin your print.

For the base, print upside down to minimize supports. I reccomend using PETG.

Only use an LED or your cap will likely melt and result in a fire hazard.
