As much as I like string lights, I think they don’t really fit the vibe of the spooky season.
I was thinking about how I could add a little halloween flair to my battery-operated LED string lights and this is the result. I’ve used translucent (not transparent) white PETG and regular black PETG.
The LEDs have a thin rubber-like coating and a outer diameter of roughly 5.3mm, so I chose to make the bore the same diameter. Due to the tolerances of the printer and the slightly squishy coating of the LEDs it is a snug fit so no glue is needed.
Happy Printing & Happy Halloween! 🎃
P.S. There is also a Christmas version: Mini Caps for Christmas LED String Lights :)
If your LEDs have a different diameter, for example 6.2mm, you can resize the model in the slicer using the following calculation:
6.2mm (your measurement) - 5.3mm (bore of the model) = 0.9mm (difference)
0.9mm / 5.3mm * 100 = 16.98%
Result: Scale the model to 116.98% and you'll get a 6.2mm bore
I would recommend to print only one cap at first to ensure that the LEDs fit.
Alternatively, you can make the bore a little larger and fix the LEDs in place with a drop of hot glue.
If you want to use my gcode file (MK3/S/S+ Generic PETG @ 240°C), you have to start the print with white filament. The printer will pause and ask you to change the filament. Insert the black filament and resume printing. There will be another pause and you have to change back to the white filament. This procedure is repeated for the top layer.
