Flames for Really Large Candles

FULL DISCLOSURE: The flame designs are a remix from the 3D_LED_Candle file I found on the internet that didn't have any identifying information. Because of this, I believe this actually qualifies as a remix. Unfortunately, I have been unable to find the location where I found the original file. Please let me know if you recognize the file or know who designed it. I would like to give proper credit to the original designer.

A friend of mine was building a really large advent wreath for their Christmas decorations this year and asked me if I knew where they could get some flames for the tops of the candles. I told her I might be able to print some so I started looking for flames to print. What I found was a small model of a votive candle that was entirely too small to use for the project. So, I cut the base off and reworked the flame part of the design.

Originally, she thought a shorter, slimmer flame would be sufficient, but once she put it on the candlestick, she decided it needed to be taller and wider, so I modified the design to meet her new specifications.  The larger flame required an adapter to fit the candlestick, so I designed the adapter as well. There is sufficient material to put screws in the flames and the adapter if you want to secure them against being blown away by the wind.

The STLs for the flame should be printed in vase mode with no bottom layers, and will require a fairly wide brim.  The inside diameter of the smaller flame will slide easily onto a two inch PVC pipe which can then be mounted inside a larger diameter pipe to complete the candle. 

The larger flame will require an adapter, which can be fastened to a board and over a piece of two inch PVC pipe.  

The diagrams show how the pieces should go together.

The flames I made were printed in vase mode using Matterhackers Translucent Orange MH Build Series PETG Filament at a temperature of 235 celsius at .2mm layer height. I used a 10mm brim on each flame. The smaller flame took about 60 minutes and the larger flame took about 90 minutes on my Sovol SV06. The adapter was printed using Matterhackers Clear MH Build Series PETG Filament.

Wiring the candles is out of my scope, but my friend used six prewired candelabra LED bulbs that plug in individually to a six port timer switch so they will come on at the appropriate time during Advent. If one knows how to program, either a Raspberry Pi or an Arduino could be used to control the lights.
