$3.00Threaded Insert and topper for Lithophane bulb
myminifactory
Using lithophanemaker.com this bulb insert and threaded topper allows for easy hanging directly on Christmas tree lights as well as battery operated mini lights. Below are simplified instructions on how I print the threaded insert directly into my bulbs. With a small raft, I have been printing these with no supports. Key settings in lithophanemaker.com's sphere maker when generating Lithophane bulbs. Set Cylinder Outer Diameter (mm) [set to 0 for no cylinder]: to 0 and Top Hole Outer Diameter (mm) [set 0 for no top hole]: to 13mm. Using your 3D Printing Slicer, align the threaded insert to your lithophane bulb opening and merge/group the objects (images attached are from Simplified3D, but Cura and other slicers have same features). I prefer printing models outside-in and have had no issues with lid screwing onto threaded inserts.
