From personal experience and what I've learned from others, there are a few DIY solutions you could try. One is using small neo magnets as spacers, which are effective and easy to organize. Another is using aluminum foil – just fold it neatly and place it on the connections as a temporary spacer. Some vapers even use springs, which seem to work well too. Each method has its pros and cons, so it might be worth experimenting to see which works best for your setup.
