not sure if you have the tools but, for your next build you can try wraps around a 2mmpost, then wraps around a 3mm post. Stick the 2mm coil through the 3mm coil and it keeps very low ohms, but has a ton more surface area and takes up smaller space int he atomizer. I call it the good ol 'double barrel' setup. saves on wick as well, u just wick through the 2mm coil but the eliquid spreads over the 2mm coil and the outer 3mm coil. my favorite 'single coil' setup (although it technically is a dual coil).
i specifically do this with 24gauge kanthal though, so im not sure how it would go with higher gauge, you could try 2mm inside a 2.5mm
