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

<p>These are a trio of Halloween themed “toppers” for some Solar Yard RGB LED lights I found at Harbor Freight ( <a href="https://www.harborfreight.com/solar-decorative-led-lights-3-pc-69462.html">https://www.harborfreight.com/solar-decorative-led-lights-3-pc-69462.html</a> ). &nbsp;There are similar lights on Amazon and other sites which will very likely be compatible. &nbsp;</p><p>The installation is simple, just remove the original clear tops and put these in their place. &nbsp;Some tape or M3x8mm screws are recommended for the Jack-O-Lantern design, to hold the back cover in place. &nbsp;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. &nbsp; &nbsp;</p><p>I printed these with minimal supports and stepped infill, and fewer layers to speed things up, especially with the Jack-O-Lantern which took 11 hours on my Ender3. &nbsp;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. &nbsp;Specifically, I used Gyroid infill at 24%, with three infill steps for the these parts and it worked well. &nbsp;I also reduced line count, as well as top/bottom layers by one. &nbsp;I did not us 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%.&nbsp;</p><p>Due to the tight fit, it would be good to check steps/mm and flow (or extrusion multiplier) so the parts will fit. &nbsp;If the holes need to be cleared out, a 3/8" drill should work to clean things up.</p><p>I used Black, Orange and Clear PLA to print these. &nbsp;Only some minor changes to increase the strength of the Jack-O-Lantern design were made since printing the models seen in the pics. &nbsp;I lost the back of the Jack-O-Lantern when I took the pics, but am re-printing it now, but it actaully looked OK without it too.</p><p>The STEP files are included for easy remixing.</p><p>Update 10/28/2021 - I broke one of the plastic connectors for the steel rods used in the posts for the solar lights. &nbsp;So I made a coupler which can be printed to hold the rods together if that happens to your lights. &nbsp;I printed the coupler in ABS since it will be outside, but PETG is a good alternative too. &nbsp;The file is just called “connector.stl” and it has a 0.25mm thick brim integrated to help with bed adhesion.</p><p>&nbsp;</p><p>If you like the Bat, I designed a smaller “Bat Bead” version which can be found here:</p><p><a href="https://www.prusaprinters.org/prints/79695-halloween-bat-bead">https://www.prusaprinters.org/prints/79695-halloween-bat-bead</a></p><p>I posted more about the design process on my blog here:</p><p><a href="http://www.mystoopidstuff.com/blog/halloween-led-bat-solar-powered">http://www.mystoopidstuff.com/blog/halloween-led-bat-solar-powered</a></p><h5><strong>I hope you like this and will post your prints if you make one, or remixes too! &nbsp;This is entered in the Halloween 2021 contest.</strong></h5><h3>&nbsp;</h3><h3><strong>Thanks for looking and HAPPY HALLOWEEN! &nbsp;</strong></h3>
