Hello and welcome. Some time ago I had such a little plastic floating disc. You insert a wick, put it in a glass, vase or jar with water and salad oil - inflame it and you've a lamp for hours to run.
Unfortunatley I've lost or misplaced the little plastic floater. Fortunatley I have a 3D-printer.
I started to design the floater from memory and ended with a little help of the internet's omniscience.
I've decided to go for a bee-themed project - because I like bees.
Step 1: The Things I've Used
- 3D-printed Floater
- Honey Jar/Glass
- Food coloring (yellow)
- Oil (rapeseed/canola oil)
- Infrared Thermometer
- 3D Printer
- PLA Filament (black)
- Software: Tinkercad, ideaMaker, paint.net
- take all necessary safety precautions while working with heat, sharp objects, electricity, vapors or resulting gases, bright light and whatever could endanger your health.
- never leave open fire/flames unattended.
Step 2: The Floating Bee Model and 3D Printing
I've found a cute bee model on thingiverse (Bee) - which I don't want to deprive you -.
I just took the rough shape as my basis and remixed it for my purposes in Tinkercad.
Well, after all it almost looks more like a six (?) leaf clover on the topside. It's fine - I like my clover bee floater.
I've 3D printed my model in black PLA-Filament on the Ender 2 with 15 % infill.
I quickly tested it's floating qualities. Since it has not fallen, everything is fine.
Step 3: The Floating Bee Light
First I've prepared the floater. I inserted the wick into the little holder of the floater and cut off +/- 15 mm of the wick.
Second, I have this nice large honey jar and
- added a little bit of the yellow food coloring
- I filled it up with water
- poured between 5 to 8 mm of the rapeseed oil on the water
- placed the floater carefully on the oil surface *)
- made sure the wick absorded the oil.
*) The floater will descend till it hits the water surface.
Step 4: The (nonscientific) Heat Test
I was wondering if the PLA-Filament could stand the hot oil, water and glass. I measured the temperature on the oil surface with an infrared thermometer at the start, after 30 minutes and after 60 minutes. I extinguished the light and immediately extracted the floater via a tweezer.
Straight after extracting, the floater has been in a steady, sturdy and solid condition. I consider that a success.
Step 5: Thank You …
... for reading, watching and paying attention.
I'm so happy with my new floater and certainly will print a few more in different designs and colors.
Please let me know if you've made one as well.
Hopefully Auf Wiedersehen in one of my next instructables.
