These are instructions to make a lantern with a simulated flame inside, using a special bulb which mimics the look of fire.
Bill of Materials:
- Bulb - see included photo 00_bulb.jpg
- Socket - see included photo 01_socket.jpg
- Cord - see included photo 02_cord.jpg - this is for the U.S., of course, your version may vary
- Heat Shrink Tubing - see included photo 03_heatshrink.jpg

See below for print settings and post-printing instructions including photos and video.
Note: you can skip printing the translucent insert (especially if you don't have a clear filament), but many of these flame bulbs can appear a little pixelated, so the translucent cyliner helps to hide that pixelation.
0.2mm, with adaptive layers (0.1mm max variation, 0.01mm step size, 200.0 threshold)
I included photos of the output:
- 05_base.jpg - this is what the ThreadedLamp_base.stl file produces
- 06_grill.jpg - this is what the ThreadedLamp_grill.stl file produces
- 07_lid.jpg - this is what the ThreadedLamp_lid.stl file produces
- 08_clear.jpg - this is what the ThreadedLamp_clear.stl file produces
The first three pieces I printed with opaque PLA, and the fourth piece with clear PETG. Each of the three opaque pieces includes threads for the pieces to be screwed together. They worked great on my Qidi X-One2. Your tolerances may vary, sorry!
I sliced each of the first three with adaptive layers in Cura 3.5.1, centered on 0.2 mm layer height, plus or minus up to 0.1 mm. The clear cylinder was just done at static 0.2 mm layers.
No supports are needed.
Step 1: Insert socket into base
Step 2: Put the clear insert into the grill
Step 3: Screw the lid onto the grill
Step 4: Twist the bulb into the socket
Step 5: Screw the grill/lid combo onto the base
Step 6: Put heat shrink tubing on the cord wires
Step 7: Twist the wires together and slide the heat shrink tubing over the exposed wires
Step 8: Apply heat to heat shrink tubing
Step 8 Finished: This is what the heat shrink tubing should look like when it has been heated
