The model is a combination of the three melting wax candle models published by Tanya Wiesner at https://www.myminifactory.com/object/3d-print-melting-candle-tea-light-candle-holders-46606. I also added negative volumes at the top of each candle to fit in deeper / wider tea lights, and added a small positive volume in-between the candles for easier printing.
The candle spaces are 42mm in diameter and 20mm in depth (if you use candles that are taller than 20mm, their sides will be visible).
Only use this with electric tea lights - I wouldn't trust a plastic candle holder with real candles!
