Purchase, Print, Prepare and Assemble the Parts.
As mentioned, the tea lights I used with this model are 37.5mm in diameter that I purchased at a local discount store. The height isn't too critical as the model uses the tea lamp as a base.
As also mentioned, I've included files for both single and dual extrusion printers. The files "Eye, Left.stl", "Eye, Right.stl", "Ghost Tealight, 1.2mm.stl" and "Mouth.stl" are the single extrusion files, the file "Ghost Tealight, 1.2mm.3mf" is the dual extrusion file.
I printed the single extrusion parts at .1mm layer height with 20% infill. I printed the dual extrusion part at .15mm layer height with 20% infill. No support or build plate adhesion was used for either version.
If you print the dual extrusion version, the model is ready to go!
But if you printed the single extrusion version, well there is some assembly required if you wish to add the eyes and mouth. Following the photographs, I glued the right eye, left eye then mouth (in that order) to the ghost using thick cyanoacrylate glue (the thick glue gives some, but not much, set up time to allow final manipulation of the parts in the ghost). While installing the eyes I used my small finger, inserted through the mouth, for support. When installing the mouth, I used my index finger, inserted through the base, for support.
With either version, press a tea light into the base and turn it on.
That's how I printed and assembled "Tea Light Ghost Lamp".
Hope you enjoy it, and happy Halloween!
