I present to you a collection of different spiral tealight holders. There are various diffrent heights and inset levels for whatever look you want. These are all very simplistic and easy to make on any printer.

There are two different types that come in differing heights: -Low : The candle is set in the bottom of the holder -High : The candle is elevated the flame is not obscured

All the sizes and types are compatible with electronic and real tealights. WARNING: PLASTIC IS FLAMMABLE Use real candles at your own risk. I am not liable for any damages caused by use of this product.

I tested a full candle with every size printed in PLA, and they worked fine. However, hypothetically, I would recommend using PETG as it is not as flammable or melty.
