DISCLAIMER this tea light is meant to be used with Flameless LED Candles and it should NOT be used with real candles unless you are using heat resistant filament or resin that is fit for that purpose.
Probably my favourite tealight. Designed to look like a flame and when you look at it from the bottom you can even see tealight in there. I probably made like 50 iterations of this one from card ones over blue foam model to resin and plaster casts. The one you see here is a 3D model of what is likely the final version of this one and if you want to see the whole process of it being designer keep an eye on mu Behance page where I'm planning to show it at some point.
As always I tried to keep it minimalist but practical so it fits in pretty much any modern environment while being practical having grooves for wax overspill if made from suitable material and with a hole on the bottom for easy extraction of tealights themselves.
They can be used without "base pads" but it depends on where you want to put them and what will you print it in. In general, I use them without it and only make pads from if I'm giving them to someone either laser cut them or cut them with a scalpel from cork or print them from TPU. Also and I always to forget to mention this if you do use base pads it will make tealights stackable.
