Just got the DIY kit v2 and I'm having a problem with the included coil jig. Although the screw-on cap fits okay without a bit inserted, it will NOT screw back on once I insert one of the bits... I've tried all six of them. Apparently the bit does not sit deep enough in the base for the cap to screw back down properly. Anybody else have this problem, and, if so, what might I do to fix it? The kit came from 3FVape out of China and it was pretty cheap, so sending it back is really not a viable option since everything else seems to function properly. Any recommendations appreciated!
