Halloween Yard Solar RGB LED Toppers (Ghost, Bat and Jack-O-Lantern)

These are a trio of Halloween themed “toppers” for some Solar Yard RGB LED lights I found at Harbor Freight ( https://www.harborfreight.com/solar-decorative-le... ). There are similar lights on Amazon and other sites which will very likely be compatible.

The installation is simple, just remove the original clear tops and put these in their place. Some tape or M3x8mm screws are recommended for the Jack-O-Lantern design, to hold the back cover in place. The Bat has screw holes for an M3x5 and M3x8mm screw, but they are not needed, since the clear insert is held in by friction.

Supplies

Black, Orange and Clear filaments

Step 1: Printing Suggestions

I printed these with minimal supports and stepped infill, and fewer walls and top/bottom layers to speed things up, especially with the Jack-O-Lantern which took 11 hours on my Ender3.Using minimal infill and a small number of wall and top/bottom layers is also helpful on the clear parts to allow them to transmit more light.

Specifically, I used Gyroid infill at 24%, with three infill steps for the these parts and it worked well. I also reduced line count, as well as top/bottom layers by one.

I did not use supports on any of the clear parts, though supports were used on the Bat and Jack-O-Lantern, but I set the overhang angle up to around 56% and used "tower" supports to help minimize them.

Due to the tight fit, it would be good to check steps/mm and flow (or extrusion multiplier) so the parts will fit.

If the holes need to be cleared out, a 3/8" drill should work to clean things up.

I used Black, Orange and Clear PLA to print these.

Step 2: HAPPY HALLOWEEN!

Only some minor changes to increase the strength of the Jack-O-Lantern design were made since printing the models seen in the pics. I lost the back of the Jack-O-Lantern when I took the pics, but am re-printing it now, but it actually looked OK without it too.

This is entered in the Halloween Contest, so please vote if you like it, thanks!

I posted some of the design process on my blog as well:
